Making Roasted Garlic Sauce at home is a great way to dress up pasta, pizza, or spaghetti squash. This tomato based sauce is flavored with bright basil, sweet yellow onion, a pinch of crushed red pepper flakes, and of course, roasted garlic.
Since the garlic takes around 30 minutes to roast, do that first. If you've never roasted garlic before - don't worry - it's a very simple process that takes only a few minutes of prep.
Things You'll Need
Small oven-safe ramekins or a muffin tin
- Aluminum foil
- Large saucepan
Blender or food processor
One whole head of garlic
- 2 Tablespoons plus 2 teaspoons olive oil, divided
- 1 small yellow onion, diced
- 1/2 teaspoon crushed red pepper flakes
1 28-ounce can of crushed tomatoes
1 teaspoon salt
- 1/2 teaspoon ground black pepper
- 1 teaspoon granulated sugar
2 teaspoons Italian seasoning
1/2 cup fresh basil, thinly sliced
Preheat oven to 400 degrees F. Peel and discard any papery outer layers on the garlic bulb, leaving the actual skin on each individual clove intact. Using a sharp knife slice a 1/4 inch off the top of the cloves, or enough to leave each clove tip exposed.
Place the garlic bulb, cut side up, in a small ramekin or muffin tin. Drizzle the olive oil over the exposed garlic tips, then cover with aluminum foil. Bake in preheated oven for 30-35 minutes, or until cloves are soft enough to be easily pressed up and out of their skin.
While the garlic roasts, prepare the tomato sauce base. Heat remaining 2 tablespoons of olive oil in a large saucepan over medium-heat. Add in the diced yellow onion and crushed red pepper; sauté, stirring occasionally, for 15 minutes, or until the onion is soft and translucent.
Add in the crushed tomatoes, salt, pepper, sugar, Italian seasoning, and basil; cook on medium-low until roasted garlic is ready. Add in roasted garlic and cook an additional 5 minutes, then transfer the sauce to a blender or food processor and pulse smooth. Taste to test for seasoning, adding more salt, pepper, or basil as needed.
