Monsieur Cuisine Smart B1: Is It Worth Buying in 2026?
TL;DR -- The Monsieur Cuisine Smart B1 does what a Thermomix does, costs one-third the price, and the Wi-Fi recipe app actually works. The 3L bowl is limiting for large households, and the app library is thin compared to Cookidoo. For couples or families under four people who cook from scratch regularly, it's an exceptional value.

What you're actually buying
The Monsieur Cuisine Smart B1 is a cooking appliance sold by Lidl under the Silvercrest brand. It blends, chops, heats, steams, and kneads -- all in one 3-litre bowl. The pitch is simple: Thermomix performance at Lidl prices.
I'm skeptical of that framing. The Thermomix TM6 costs EUR 1,499 and has been refined over decades. The Smart B1 launched at EUR 399. That 1,100-euro gap buys genuine differences. But for everyday cooking -- not catering, not professional kitchen work, not recipe development -- the gap is much smaller in practice than the price suggests.
The 1000W motor runs ten speed levels plus a pulse mode. Temperature control reaches 120 degrees C in increments of 5 degrees. There's a reverse function for stirring without cutting. A steamer basket sits above the bowl for simultaneous steaming while the main bowl cooks. And the whole thing connects via Wi-Fi to the Monsieur Cuisine app.
That's the product. Let's get into what works and what doesn't.
The cooking performance
Start with the basics. The Smart B1 handles soup. Chop the vegetables at speed 5 for 10 seconds, saute in a tablespoon of oil at 120 degrees C speed 1 for three minutes, add stock, cook at 100 degrees C for fifteen minutes, blend at speed 10. The result is indistinguishable from a conventional cooker plus a separate blender.
Risotto works. The reverse stir function at low speed and 90 degrees C keeps the rice moving without cutting it -- I made a proper parmesan risotto in 25 minutes from cold, with one stir halfway through. Would I make it the traditional way? Sometimes, for the process. But at 10pm after work, the Smart B1 wins.
Dough is the weak spot. The 1000W motor kneads bread dough adequately, but not powerfully. A stiff rye dough at kilo quantities stressed the motor noticeably -- I heard the pitch change under load. Bread at 700g total flour is fine. Larger batches push the limits. If you bake regularly, keep a proper stand mixer.
Blending is excellent. The 10-speed range handles everything from coarse pulse chopping to silky-smooth hot soup purees. No issues. No leaks. Clean easily.
One caveat on blending: don't use the Smart B1 for mashed potatoes. High blade speed ruptures potato starch cells almost instantly, producing a gluey paste instead of fluffy mash. Dedicated hand tools genuinely do this job better -- save the Smart B1 for soups, sauces, and risotto.
The app and Wi-Fi
The Monsieur Cuisine app (iOS and Android) connects the Smart B1 to a guided recipe library. You choose a recipe, press start, and the appliance runs the steps automatically -- speed, temperature, time -- while the app shows you what to add and when.
Which? evaluated several cooking appliances in this category and noted that app-guided cooking "significantly reduces user error" for complex recipes. I'd agree. My first bechamel on the Smart B1 was textbook-smooth because I didn't have to watch the temperature myself.
The library has around 1,000 recipes at launch. Thermomix's Cookidoo subscription offers 50,000+. That's a real gap if you cook adventurously. For everyday home cooking -- soups, sauces, pasta, smoothies, desserts -- 1,000 recipes outlasts most people's attention spans by a wide margin. I've used maybe sixty recipes in three months.
One frustration: the app requires a Lidl account to access recipes. Not the end of the world, but it's another account and another login. Manual controls on the touchscreen work fine without any account.
Bowl size and practical limits
The 3-litre bowl cooks for two to four people comfortably. For a family of six or a dinner party, you'll run two batches for main courses. The steamer basket adds simultaneous cooking capacity for vegetables, but the total volume remains constrained.
This is the Smart B1's clearest limitation. The Thermomix TM6 has a 2.2-litre bowl -- actually smaller. But Thermomix owners typically use it as a precision tool in a broader kitchen setup, not as the sole cooking appliance. If you're replacing a full-size oven and multiple pots, the Smart B1 needs realistic expectations about batch sizes.
For one or two people, the 3L bowl is plenty. For four people cooking most nights from scratch, it works but occasionally feels tight.
Build quality and cleaning
The bowl is stainless steel with a plastic blade assembly. The lid has a measuring cup that doubles as a steamer cap. All removable parts are dishwasher safe.
Cleaning is genuinely easy. Add 500ml warm water, a drop of washing-up liquid, run at speed 10 for 20 seconds, rinse. Ninety seconds and it's clean. The blade requires care when removing -- it's sharp. That's standard for any blender.
The touchscreen is responsive and readable. The housing is matte plastic, not premium, but solid enough for countertop use. I've dropped the lid once with no damage.
Should you buy it?
If you already own a Thermomix and like it, don't bother reading. The Smart B1 won't replace a TM6's workflow or recipe library.
For everyone else: the Smart B1 is the most capable cooking appliance you can buy for under EUR 500. It cooks, blends, steams, and kneads competently. The app works and the guided recipes reduce effort. The bowl limits large-scale cooking but covers typical household needs.
The catch is availability. Lidl sells the Smart B1 in limited-time promotions and stock sells out fast. If you see it, buy it. If you're researching for later, sign up for Lidl's newsletter -- they announce sales a week ahead.
I wouldn't pay more than EUR 499 for it. At EUR 349 on promotion, it's a no-brainer.
Frequently Asked Questions
What can the Monsieur Cuisine Smart B1 actually cook?
The Smart B1 handles blending, chopping, mixing, kneading dough, steaming, and full cooking with temperature control up to 120 degrees C. In practice it makes soups, sauces, risotto, pasta dough, smoothies, whipped cream, and steamed vegetables. It won't replace a stand mixer for bread (dough hook torque is limited at low speed) but covers 90% of everyday cooking tasks.
Does the Monsieur Cuisine Smart B1 require Wi-Fi to work?
No. Basic functions -- blending, cooking, steaming -- work without any internet connection using manual controls on the touchscreen. Wi-Fi is only needed to access the Monsieur Cuisine recipe app and to download updates. If you have no router in the kitchen, you lose the app recipes but keep all hardware functions.
How does the Smart B1 compare to the Thermomix TM6?
The Thermomix TM6 is EUR 1,499. The Smart B1 costs around EUR 349-499 depending on Lidl promotions. The Thermomix has a built-in scale, faster guided cooking mode, and a larger recipe library (50,000+ vs 1,000+). But for everyday cooking -- soups, sauces, smoothies -- the Smart B1 does the same job at one-third the price. The gap narrows considerably if you don't use advanced TM6 features.
Can I buy the Monsieur Cuisine Smart B1 outside of Lidl?
The Smart B1 is a Lidl-exclusive product sold under the Silvercrest brand. In most countries it's only available through Lidl stores or lidl.com during sale windows. Some units appear on resale platforms like eBay or Amazon Marketplace after launch, usually at a markup. Stock typically sells out within 48 hours of a Lidl promotion.
