Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Pappardelle and Provençal Sauce
Ingredients
Directions
Prepare the vegetables
Cut each onion into eight wedges through the root end, to hold them together during cooking.
Put the onions into a saucepan with the stock and garlic.
Bring to a boil, cover and simmer for 5 minutes until tender.
Make the sauce
Add the red wine, zucchini, yellow pepper, tomatoes, thyme, sugar and seasoning.
Bring to a boil and cook gently for 5-7 minutes, shaking the pan occasionally to coat the vegetables with the sauce.
Do NOT overcook the vegetables; they are much nicer if they remain slightly crunchy.
Cook the pasta and serve
Cook the pasta in a large pot of boiling, salted water according to the package instructions, until al dente.
Drain thoroughly.
Transfer the pasta to warmed serving plates and top with the vegetables.
Garnish with fresh thyme and chopped black olives.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red onions
- Soften and sweeten as they cook, giving the sauce body and mild sweetness.
- Red wine
- Adds acidity and depth of flavour to the sauce as it reduces.
- Zucchini
- Contributes moisture and tender texture to the vegetable topping.
- Yellow bell pepper
- Adds sweetness and a fresh, vegetal flavour to the sauce.
- Canned tomatoes
- Provide the main liquid, acidity and body of the sauce.
- Pappardelle
- Carries the sauce, with its broad ribbons holding the vegetables well.
The step that matters
Do not overcook the vegetables. Zucchini and pepper turn soft and watery with long cooking, losing their texture and fresh flavour. Keeping them slightly crunchy preserves structure and keeps the sauce from becoming mushy.
