Ninja ST100 vs ST101 Foodi Flip Toaster: Which One Is Actually Worth Buying in 2026?

Quick verdict: After testing both models side-by-side for three weeks, the Ninja ST101 is the better long-term buy because it unlocks extra cooking modes like Reheat and Defrost that actually change how you use the machine. The Ninja ST100 is usually cheaper and works great for basic toasting, but it feels limited once you start reheating leftovers or cooking frozen snacks.

I used both units in my own kitchen, cooking the same foods back-to-back to see if those extra presets on the ST101 truly matter or if they’re just marketing labels. Spoiler: they do make a difference.

What Separates These Two Models in Real Life

The main difference between the Ninja ST100 and ST101 is that both share the same 1500-watt heating system, but the ST101 unlocks more functionality through specialized presets like Reheat and Defrost. The ST100 is the base model with Toast, Bagel, Bake, and Broil only.

In simple terms:

• ST100: Great for toast and simple oven snacks.
• ST101: More flexible for daily cooking, leftovers, and frozen foods.

Design & Build Quality

Both models share the same stainless steel body and flip design. Flip it up for toaster mode. Flip it down for oven mode. It’s a clever space-saving concept that actually works.

On my counter:

• They feel solid – no flimsy plastic.
• Knobs have good resistance.
• Door hinge feels strong even after daily use.

The ST100 is slightly narrower, but the difference is small. If you have extremely limited counter space, the ST100 might fit better. Otherwise, you won’t notice it.

My Kitchen Test Results

1. Bread Toast Test

I toasted thick sourdough and regular white bread on both machines at shade level 4.

• ST100: Even browning, slightly darker at the bottom.
• ST101: Same browning pattern, but Defrost mode handled frozen bread better.

Conclusion: The flip design does NOT cause uneven toasting. Both perform like a premium toaster.

2. Frozen Pizza Bagel Test

I cooked standard frozen pizza bagels straight from the freezer.

• Cooking time: 9 minutes
• No preheat needed
• Cheese melted evenly
• Bottom crisp, top golden

Winner: ST101, because Reheat mode warmed leftovers perfectly without over-browning.

3. Leftover Slice of Pizza

This test alone sold me on the ST101.

• ST100 (Bake mode): reheated pizza but crust got too hard.
• ST101 (Reheat mode): soft inside, crispy bottom, no burnt cheese.

This is where presets actually matter.

4. Noise Level

• Timer beep: loud enough to hear from another room.
• Fan: runs in oven mode on both models.
• Sound level: similar to a microwave fan.

Not annoying, just noticeable.

Daily Use Experience

I tested these units side-by-side for three weeks. Mornings were toast and bagels. Evenings were leftovers, frozen snacks, and quick bakes.

What I learned:

• ST100 feels limited after a week.
• ST101 becomes a daily-use appliance.
• I stopped using my microwave for reheating.

Real talk: once you use Reheat mode, you won’t go back.

Ninja ST100 Review (Hands-On)

The ST100 is a fantastic basic toaster oven. It does exactly what it promises:

• Fast toasting
• Even browning
• Fits thick artisan bread
• Simple controls

I used it mostly for:

• Morning toast
• Bagels
• Chicken nuggets
• Open-face sandwiches

Where it falls short is reheating. Without a Reheat preset, you have to guess between Bake and Broil. It works, but it’s not foolproof.

Pros

• Lower price
• Compact size
• Great toast quality
• No preheat needed

Cons

• No Reheat mode
• No Defrost preset
• Feels limited over time

Ninja ST101 Review (Hands-On)

The ST101 feels like the complete version of this product. Same power, same design, but smarter presets.

I used it for:

• Leftover pizza
• Frozen waffles
• Chicken wings
• Garlic bread

Defrost mode saved me time. Reheat mode saved my food from drying out.

This is the model I kept on my counter after testing.

Pros

• Reheat mode works perfectly
• Defrost handles frozen bread well
• Same fast heating
• Very versatile

Cons

• Costs slightly more
• Still only 2 slices

Cleaning & Maintenance

Both models are easy to clean.

• Crumb tray slides out
• Interior wipes clean
• No grease buildup

Pro tip: Empty crumb tray every 3 days if you toast daily.

Energy Efficiency

Because they don’t require preheating, both models use less electricity than a full oven.

• 9 minutes cooking vs 15 minutes oven
• No wasted heat
• Lower power bill

Who Should Buy ST100?

• You only make toast
• You want the lowest price
• You rarely reheat food
• You have very limited counter space

Who Should Buy ST101?

• You reheat leftovers daily
• You cook frozen snacks
• You want microwave replacement
• You want more control

FAQs

Do both models use 1500 watts?
Yes. Same power system.

Is ST101 faster?
Same speed, better presets.

Does ST100 bake?
Yes, but no reheat mode.

Can they cook frozen food?
Yes. ST101 does it better.

Final Verdict

If you’re deciding between Ninja ST100 vs ST101, here’s my honest recommendation:

Buy the ST101 unless the price difference is huge.

The extra presets aren’t gimmicks. They actually improve how food reheats and cooks. After using both daily, the ST100 felt outdated.

For 2026, the ST101 is simply the smarter choice.
