A countertop oven can save space only if it replaces appliances you actually use. The CIARRA 12-in-1 Countertop Steam Oven with Air Fryer, also sold as the Nosh Oven Pro CASO24-W, combines steam cooking, air frying, baking, reheating, dehydrating, fermenting, and other functions in a 25.4-quart appliance. Its biggest strength is the combination of steam and dry-heat cooking in one machine, while its main tradeoff is that a 25.4QT countertop oven still needs meaningful counter space. This review explains the specifications, functions, cleaning needs, limitations, and buyer situations that matter before you decide.
Quick Verdict
Rating: 8.4/10, Recommended with caveats
Best For: Families and home cooks who want steam, air-fry, bake, reheat, ferment, and dehydrate functions in one countertop appliance.
Bottom Line: The CIARRA Nosh Oven Pro stands out for its 25.4QT capacity and broad cooking-mode selection. The main caveats are its countertop footprint and small specification differences between the current Amazon and manufacturer listings, so check the exact listing details before ordering.
Editorial note: This review evaluates published product specifications and documented features. It does not claim hands-on laboratory testing.

Key Takeaways
- The 25.4QT Nosh Oven Pro combines steam cooking, air frying, baking, reheating, dehydrating, fermenting, and related functions in one countertop appliance.
- Steam, Rapid Steam, and Steam Convection give you more moisture control than a basic dry-heat air fryer or toaster oven.
- The Amazon listing specifies 1500W, an 85°F to 430°F temperature range, touch-and-knob controls, and a 2-year warranty.
- The included basket, baking pan, rack, water tank, oven mitt, and recipe material support several cooking methods without requiring a separate accessory purchase for basic use.
- It makes the most sense when you will regularly use several of its cooking modes. Buyers who only want basic air frying may prefer a smaller, simpler appliance.
What Is the CIARRA Nosh Oven Pro?
The CIARRA Nosh Oven Pro CASO24-W is a 25.4-quart countertop steam oven and air-fryer combination. Instead of focusing on a single cooking method, it gives you steam-based modes alongside convection-style dry heating, baking, air frying, warming, dehydrating, fermenting, reheating, cleaning, and preset programs.
That combination is useful when you want one appliance to cover weekday meals, baked foods, reheating, vegetables, crispy snacks, proofing or fermentation tasks, and steam-assisted cooking. The wider feature set also means there is more to learn than with a basic basket air fryer.
Discover the Benefits of the CIARRA 12-in-1 Steam Oven
The main reason to consider this oven is not simply that it has many menu options. Its more meaningful advantage is the ability to switch between steam, convection heat, and air frying without changing appliances.
Steam cooking is useful for foods where moisture matters, while air frying and convection cooking focus on browning and surface crispness. Steam Convection gives you another option when you want moisture during part of the cooking process without giving up circulating hot air.
The 25.4-quart capacity also makes this more family-oriented than a small single-basket air fryer. You gain more cooking space, although you also need enough permanent counter area and clearance around the appliance.
In-Depth Look at Cooking Functions and Modes
| Cooking Function | Best Use |
|---|---|
| Steam | Moist cooking for vegetables, fish, dumplings, and similar foods. |
| Rapid Steam | When you want steam generated quickly. |
| Steam Convection | Combines moisture with circulating hot air. |
| Air Fry | Crisping foods with hot-air circulation and less added oil than deep frying. |
| Bake | Bread, pastries, casseroles, and other baked dishes. |
| Dehydrate | Low-temperature drying of suitable foods. |
| Ferment | Controlled low-temperature tasks such as dough fermentation. |
| Reheat / Keep Warm | Warming prepared food without using a separate appliance. |
| Clean / Sterilize / Preset | Utility and programmed functions for maintenance and supported cooking tasks. |
The Amazon listing gives the oven an 85°F to 430°F operating range. That low end is especially relevant to fermentation and dehydration, while the higher end supports baking, roasting-style cooking, and air frying.
Pro Tip: Choose the cooking mode based on the texture you want. Use steam when moisture is the priority, Air Fry when surface crispness matters, and Steam Convection when you want a balance of moisture and browning.
How Easy Is the CIARRA to Use and Maintain?
The oven uses a combination of touch controls and a rotary knob, which is more practical than forcing every adjustment through a touchscreen. Once you understand where the main modes are located, you can select the function and adjust cooking settings from the front control panel.
The built-in steam-cleaning function is another useful feature for a steam-capable appliance. It can help loosen residue inside the cooking chamber, but it does not remove the need for normal wiping and accessory cleaning.
Allow the oven to cool before routine cleaning and follow CIARRA’s instructions for the water system, removable accessories, and interior surfaces. Avoid abrasive methods that could damage finished surfaces.
Versatility: Replacing Multiple Kitchen Appliances
The strongest case for the CIARRA is appliance consolidation. Depending on your cooking habits, it can handle jobs you might otherwise assign to a countertop oven, steamer, air fryer, dehydrator, warming appliance, or proofing setup.
| Typical Appliance | CIARRA Function |
|---|---|
| Air fryer | Air Fry |
| Food steamer | Steam / Rapid Steam |
| Countertop oven | Bake / Steam Convection |
| Dehydrator | Dehydrate |
| Proofing setup | Ferment |
This does not mean it will replace every full-size appliance for every household. Large-batch baking, specialized dehydration, or cooking multiple large dishes at once may still be better suited to dedicated equipment.
What’s Included: Accessories and Recipe Ideas
The CIARRA package includes the core accessories needed for its major cooking modes: an air fryer basket, baking pan, oven rack, oven mitt, water tank, and recipe material. That gives you separate surfaces for airflow-focused cooking, baking, and rack-based meals.
The recipe material can also help you understand which modes fit different foods. For best results, treat the included recipes as starting points and adjust time according to food thickness, quantity, starting temperature, and your preferred doneness.
Who Should Buy It?
Best For
- Families who want a 25.4QT countertop cooking chamber.
- Home cooks who plan to use both steam and dry-heat cooking modes.
- Buyers trying to combine an air fryer, steamer, countertop oven, and several secondary functions.
Skip If
- You only need a small air fryer for one or two portions.
- Your available counter space is very limited.
- You prefer a basic appliance with only a few controls and functions.
How It Performs in Real Use
For Everyday Family Meals
The 25.4QT capacity gives you more flexibility than a compact basket-style air fryer. You can use the larger chamber for foods that need a rack, pan, or broader cooking surface, making the oven more suitable for mixed family meal preparation.
For Foods That Dry Out Easily
Steam and Steam Convection are the important modes here. Instead of relying only on dry circulating air, you can choose a moisture-based cooking method when the food benefits from a softer exterior or more moisture during cooking.
For Crispy Snacks and Reheating
Air Fry provides the dry circulating heat needed for browning and crisping. Reheat gives you another dedicated option for prepared food, so you do not have to choose a full baking cycle every time you warm leftovers.
For Baking, Fermentation, and Dehydrating
The broad listed temperature range makes the oven useful beyond dinner. The Ferment and Dehydrate modes target lower-temperature tasks, while Bake handles conventional oven-style recipes within the appliance’s capacity and temperature limits.
Setup Tips Before First Use
- Measure the counter area before ordering and leave the ventilation clearance required by the current CIARRA manual.
- Place the appliance on a stable, heat-resistant surface.
- Wash or clean removable food-contact accessories according to the manual before their first use.
- Learn the difference between Steam, Steam Convection, and Air Fry before cooking a full meal.
- Check the water tank before selecting a steam-dependent program.
- Keep ventilation openings unobstructed while the oven is operating.
Food and Appliance Safety
This is a high-temperature electrical cooking appliance, so normal countertop-oven precautions apply. Keep the unit on a stable surface, avoid blocking ventilation, use heat protection when handling hot trays or racks, and allow components to cool before cleaning.
The oven’s Sterilize function should be used only for items that the manufacturer identifies as compatible with that function. A steam program does not automatically make every plastic, container, utensil, or baby-related item safe for high-temperature treatment.
The CIARRA should also not be treated as pressure-canning equipment. If you preserve food through canning, use equipment and processing instructions specifically designed for the approved canning method.
Pros and Cons
Pros
- 25.4QT capacity suits larger countertop cooking tasks.
- Combines steam, convection, air frying, baking, dehydration, fermentation, and reheating.
- Touch controls plus a rotary knob provide two ways to navigate settings.
- Steam-cleaning mode can make routine interior maintenance easier.
- Comes with the main basket, pan, rack, water-tank, mitt, and recipe accessories needed for its core functions.
Cons
- A 25.4QT multifunction oven requires more counter space than a compact air fryer.
- The large number of modes creates a learning curve if you prefer simple controls.
- Amazon and CIARRA currently publish slightly different wattage and maximum-temperature figures, so detail-focused buyers should confirm the current specification sheet.
Is It Worth the Price?
The CIARRA Nosh Oven Pro makes the strongest value case as a premium multifunction countertop appliance, not as a basic air fryer. You are paying for the combination of a larger chamber, steam system, dry-heat modes, low-temperature functions, accessories, and cleaning features.
It offers better value when you expect to use several of those capabilities every week. If your routine consists almost entirely of reheating snacks or air frying small portions, a simpler appliance will probably give you more value with less counter-space commitment.
How It Compares to Alternatives
The Ninja Combi is another option for buyers who want steam-assisted cooking and air frying, with a stronger emphasis on complete multicooker-style meals. The Anova Precision Oven 2.0 is more focused on precision combi-oven cooking and advanced steam control.
The CIARRA makes the most sense when you specifically want its 25.4QT format, traditional countertop-oven layout, steam modes, air frying, fermentation, dehydration, and self-cleaning functions together. Compare physical size, control style, accessories, and the cooking modes you will actually use rather than choosing by function count alone.
Frequently Asked Questions
What is the capacity of the CIARRA Nosh Oven Pro?
The CASO24-W is listed with a 25.4-quart cooking capacity. That puts it in the larger countertop-appliance category and gives you more room than a small basket air fryer.
Can the CIARRA replace a separate air fryer and steamer?
It includes dedicated Air Fry, Steam, Rapid Steam, and Steam Convection functions, so it can cover many jobs normally handled by those appliances. A dedicated device may still be preferable if you need specialized capacity or use only one cooking method.
What temperature range does it have?
The Amazon listing tied to this review currently states 85°F to 430°F. CIARRA’s direct product page has published a higher 450°F maximum, so check the current specification shown on the listing if that difference affects your recipes.
Does the CIARRA steam oven clean itself?
It includes a steam-based Clean function designed to help with interior maintenance. You should still wipe the oven and clean removable food-contact accessories according to CIARRA’s care instructions.
What warranty does the CASO24-W include?
Amazon currently lists a 2-year warranty for model CASO24-W. Review the warranty information on the listing and documentation supplied with your unit because warranty terms can vary by market or seller.
Can you use the CIARRA oven for home canning?
Do not treat the oven’s steam function as a substitute for approved canning equipment. Food-preservation canning requires the correct equipment and processing method for the food being preserved.
Who should skip this 12-in-1 oven?
Skip it if you have very limited counter space, only need a compact air fryer, or want the simplest possible controls. Its value comes from using several functions, so paying for twelve modes makes less sense if you will regularly use only one or two.
The Bottom Line
The CIARRA 12-in-1 Nosh Oven Pro CASO24-W is a strong option for households that want steam cooking, air frying, baking, reheating, fermentation, and dehydration in one 25.4QT countertop appliance. Its versatility and steam system are the main strengths, while its larger footprint, learning curve, and current specification differences between sales pages are the main reasons to compare carefully before ordering.
For buyers who will use several of those functions regularly, the overall verdict remains Recommended with caveats.
