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 ↓
Lee Towe's Pasta Sauce
Ingredients
Directions
Prepare
Heat a medium stir-fry pan over medium-high heat and lightly spray the pan with cooking spray.
Sauté the onions until tender.
Remove the onions from the pan.
Make the sauce
Add the mushrooms and sauté until they sweat and release liquid.
Return the onions to the pan, add the garlic paste, water or vegetable broth, nutritional yeast, and grated parmesan cheese; bring to a boil.
Blend the cornstarch with a couple tablespoons of cold water, then pour into the pan to thicken the sauce.
If more liquid is desired, increase the amount of water or broth added.
Serve
Toss the sauce with cooked pasta of choice.
Sprinkle servings with additional nutritional yeast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Release moisture as they sweat, adding savory body to the sauce.
- Cornstarch
- Thickens the sauce when heated with liquid, giving it a clingy texture.
- Nutritional yeast
- Adds savory, cheese-like flavor to the sauce.
- Onions
- Soften and add sweetness and aromatic depth to the base.
The step that matters
Blending the cornstarch. Cornstarch must be fully mixed into cold water before it goes into the hot pan; added dry or lumpy, it clumps and thickens unevenly. It thickens only when the liquid reaches a boil.
