Steps

Slice onions thinly. Mince garlic. Measure butter, wine, and broth.

⏱ 5 min💡 Use a sharp knife or the grating disc on Food Processor mode for even slicing.

Install the stirring attachment into the GastroLab bowl. Add butter and sliced onions. Set to Manual mode, 60°C, Speed 1, for 20 minutes to caramelize onions gently.

GastroLab:

Install stirring attachment. Add butter and onions to bowl. Install lid. On touchscreen: select Manual → set Temperature 60°C, Speed 1, Time 20 min → press knob to start.

⏱ 20 min💡 Low heat and slow stirring will release the onions' natural sweetness without burning them.

After 20 minutes, the onions will be softened and starting to caramelize. Add minced garlic, wine, and broth. Continue on Manual mode, 95°C, Speed 2, for 10 more minutes to reduce the liquid slightly and blend flavors.

GastroLab:

Pause the device (press knob once). Add minced garlic, white wine, and broth to the bowl. On touchscreen: select Manual → set Temperature 95°C, Speed 2, Time 10 min → press knob to start.

⏱ 10 min💡 The higher temperature will gently simmer the sauce and evaporate some of the wine's acidity.

While the sauce finishes, bring a large pot of salted water to a boil and cook pasta according to package directions (usually 10–12 minutes) until al dente. Drain and set aside.

⏱ 12 min💡 Cooking pasta separately ensures you have full control over its texture.

When the onion sauce is ready, remove the stirring attachment. Transfer cooked pasta into the GastroLab bowl with the caramelized onion sauce. Use Manual mode, 70°C, Speed 1, for 2 minutes to gently combine and coat the pasta.

GastroLab:

Remove stirring attachment. Add cooked pasta to the onion sauce in the bowl. Install lid. On touchscreen: select Manual → set Temperature 70°C, Speed 1, Time 2 min → press knob to start.

⏱ 2 min💡 Gentle tossing ensures every strand of pasta is coated evenly without breaking it.

Transfer pasta to serving plates or bowls. Top with grated Parmesan cheese and fresh parsley if desired.

⏱ 3 min💡 Serve immediately while the pasta is warm and the sauce is silky.

Chef's note: This dish celebrates the simplicity of Italian cooking. The caramelized onions become sweet and rich—there's no need for cream or tomato sauce. If you prefer a thinner sauce, add a splash more broth. A drizzle of good olive oil at the table elevates it further.
