Tomato pasta in the Thermomix® only works well when the roux is ready before the tomatoes go in. Here is how we get it right every time: melt 40 g butter at 70°C, sweat 20 g flour for 3 minutes at 80°C on speed 1, then add 200 g tomatoes, 3 tbsp tomato puree and 600 g vegetable stock and blend for 10 seconds, increasing gradually to speed 8. Finally, add 200 g short pasta and cook for 10 minutes at 90°C in reverse direction on the gentle stir setting. That gives you 3 servings in 22 minutes.
We have been making this recipe for years because it puts real food on the table in just over 20 minutes without getting a second pot dirty. The one point where most other one-pot versions fall short: if you throw the tomatoes and flour in at the same time, you end up with lumps instead of sauce. We take the detour via a roux, and that is exactly what keeps the sauce smooth from the very first second. If you prefer the classic version without a roux, you will find it in our One-Pot Pasta with the Thermomix®.

Why the roux comes before the tomatoes
Flour needs fat and heat in order to bind. If you stir the 20 g flour directly into the 600 g stock, it gelatinises unevenly and forms lumps that even blending cannot smooth out. The roux turns the individual starch molecules into a stable emulsion: first the butter melts, then it coats every grain of flour, and only those coated grains later disperse into the liquid without clumping.
This is exactly where our approach differs from most recipes in the Vorwerk community and on recipe portals: there, passata or tomato juice goes into the mixing bowl at the same time as everything else. That works quickly, but it only thickens by reducing the liquid. Our roux binds actively and immediately, which means the sauce stays velvety even as the pasta releases starch during cooking.
At 80°C the flour particles toast lightly. This gives the sauce more depth than simply cooked flour. Three minutes is exactly right: less and it tastes of raw flour, more than five minutes and the roux turns bitter and dark.
Getting the tomato puree right as an umami booster
Fresh tomatoes alone have little body. The 3 tbsp tomato puree brings concentrated glutamates that make the flavour rounder and more savoury. Three tablespoons is the minimum for three servings. If you want a more intense result, toast the puree briefly first: simply let it run with the flour for 30 seconds at 80°C on speed 1 before the stock goes in. This takes the sharp acidity out of the puree.
We add the oregano, basil and sweet paprika directly with the tomatoes into the mixing bowl, not at the end. Blending distributes them evenly and releases the essential oils. If you add the spices only after cooking, you can taste individual pockets of spice rather than a rounded sauce. The half teaspoon of salt also belongs in the sauce from the start: it draws moisture from the tomatoes and seasons from within while the pasta cooks.
Reverse direction and short pasta keep the pasta intact
At 10 minutes at 90°C in reverse direction on the gentle stir setting the pasta cooks through without breaking apart. Reverse direction is not a minor detail here, it is the key: the blade rotates blunt-edge first and gently pushes the pasta through the sauce rather than cutting it. Use normal direction and you will end up with pasta confetti in the pot.
The second detail is the ratio: 200 g pasta to 600 g stock is exactly 1:3. More liquid makes the sauce thin, less leaves the pasta sitting dry on top. Short pasta such as penne or fusilli also works better than spaghetti: long pasta breaks too easily in the mixing bowl and is hard to get out in one piece. The 10-minute cooking time suits all standard durum wheat pasta.
Three common pitfalls with Thermomix® tomato pasta
The sauce is lumpy even after blending
This is almost always because the roux was skipped or not cooked long enough. Flour that is simply stirred into hot liquid immediately absorbs water on the surface and stays dry and encapsulated inside.
Our fix: Allow the full 3 minutes at 80°C on speed 1 for the flour, then add the stock. If lumps do appear, blend for 5 seconds at speed 6 before the pasta goes in.
The pasta turns mushy or falls apart
This happens with normal direction, with too high a speed, or when using spaghetti. Leaving the pasta to sit in the hot sauce after cooking also draws in more water and softens it further.
Our fix: Always use reverse direction and the gentle stir setting, never higher. After the 10 minutes, serve straight away or open the mixing bowl lid so the residual heat does not keep cooking the pasta. Short pasta is more forgiving than long.
The sauce is too thin or too thick
Different types of pasta absorb different amounts of liquid. Wholemeal pasta and macaroni need more, smooth penne need less.
Our fix: If the sauce is too thin, cook for 2 more minutes at 90°C without the measuring cup so the steam can escape. Too thick: simply stir in 50 g of hot stock. The basic 1:3 ratio remains the best starting point.
Four variations we make regularly
Creamy with double cream: Replace 50 g of the stock with double cream or cream cheese. This turns the tomato pasta into a tomato and cream sauce that children often prefer.
With minced meat: After the butter, brown 200 g minced meat for 5 minutes at 100°C on speed 1 in reverse direction, remove, then add it back in with the pasta after blending. This gives you a quick Bolognese-style dish.
Mediterranean: Chop half an onion and a garlic clove for 3 seconds at speed 5 before the butter and sweat them in the butter. Add 50 g of finely diced sun-dried tomatoes or a few olives.
Spicy: Blend half a chilli or 1/2 tsp chilli flakes in with the tomatoes. For an arrabbiata flavour, add a second garlic clove as well.
What we like to serve with the tomato pasta
Grated Parmesan or Pecorino scattered over the hot pasta melts slightly and adds a salty savouriness. We tear fresh basil leaves over the top at the table, never during cooking, because heat destroys the aroma. If you are looking for more quick Thermomix® pasta, we have One-Pot Salmon Pasta and All-in-One Cheese, Ham and Cream Pasta.
As a quick lunch the tomato pasta is a complete meal on its own. In the evenings we often add a simple green salad, and on cold days we switch to our creamy potato soup with frankfurters. If you fancy something different again, our mustard eggs are also ready in just over 20 minutes and likewise use a roux as the base.
How long the tomato pasta keeps
In a sealed container the pasta keeps for 2 to 3 days in the fridge. When reheating, we always add a little water or stock, because the pasta continues to absorb liquid overnight and will otherwise be dry. 50 to 80 ml per serving is enough. Heat in the microwave covered for 2 minutes, or in a saucepan over medium heat, stirring.
Freezing does not work well with this recipe. The sauce separates on thawing and the pasta becomes starchy. If you want to cook ahead, it is better to freeze only the finished sauce without pasta (for up to 3 months) and then cook fresh pasta in it when needed.
Goes well with: Parmesan and basil.
