# What you need:

01 - 3 large whole garlic bulbs
02 - 1 medium yellow onion, finely chopped
03 - 1 (14 oz) can diced tomatoes
04 - 2 tbsp fresh basil, chopped (plus extra for garnish)

→ Dairy

05 - 1/4 cup heavy cream
06 - 2 tbsp unsalted butter
07 - 1/4 cup grated Parmesan cheese (plus more for serving)

→ Pantry

08 - 12 oz dried pasta (spaghetti, linguine, or fettuccine)
09 - 2 tbsp olive oil (plus extra for drizzling)
10 - 1/2 tsp salt
11 - 1/4 tsp freshly ground black pepper
12 - 1/2 tsp crushed red pepper flakes (optional)

# Steps to follow:

01 - Preheat the oven to 400°F.
02 - Slice the tops off the garlic bulbs to expose the cloves. Place each bulb on a piece of foil, drizzle with olive oil, and wrap tightly.
03 - Roast the garlic bulbs in the oven for 35–40 minutes until golden and soft. Allow to cool slightly.
04 - Squeeze the roasted garlic cloves from their skins into a bowl and mash to a paste.
05 - Cook the pasta in salted boiling water according to package instructions. Reserve 1/2 cup of pasta water before draining.
06 - In a large skillet, heat 2 tbsp olive oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes.
07 - Stir in the mashed roasted garlic and cook for 1 minute until fragrant.
08 - Add the diced tomatoes, basil, salt, pepper, and red pepper flakes (if using). Simmer for 8–10 minutes to blend flavors.
09 - Stir in the butter and cream. Simmer for 2 minutes, then add the Parmesan cheese.
10 - Toss the cooked pasta into the sauce, adding reserved pasta water as needed for creaminess. Serve immediately, garnished with extra basil and Parmesan.

# Expert tips:

01 -
  • Roasting transforms garlic from pungent and sharp into something incredibly sweet and mellow, almost like a savory spread.
  • The sauce comes together in under an hour but tastes like it simmered all day.
  • This recipe turns humble ingredients into something that feels luxurious and restaurant worthy.
02 -
  • Do not rush roasting the garlic, those 35 to 40 minutes are essential for developing the sweet mellow flavor that makes this sauce special.
  • Reserving pasta water is not optional, the starchy water is what helps the sauce cling to every strand of pasta.
  • The sauce thickens quickly as it cools, so adjust consistency with pasta water right before serving.
03 -
  • If the garlic cloves are still slightly firm after roasting, wrap them back up and return to the oven for 5 to 10 more minutes.
  • For a vegan version, coconut cream or cashew cream works surprisingly well as a substitute for heavy cream.
  • Roasting extra garlic bulbs is always a good idea, the paste can be used on bread, in mashed potatoes, or stirred into soups.
