3 lb fresh tomatoes
8 cloves garlic, coarsely chopped
1/3 cup olive oil
3/4 tsp salt
1/2 tsp black pepper
1/2 tsp red pepper flakes

Directions

3. Add the chopped garlic evenly over the tomatoes.

4. Drizzle with olive oil and sprinkle with salt, black pepper, and red pepper flakes. Toss everything together until well coated and spread evenly in the dish.

5. Roast in the oven for 45 minutes, or until the tomatoes are soft and caramelized in spots.

6. Let the roasted tomatoes cool slightly.

7. Use a slotted spoon to transfer the tomatoes and garlic to a blender.

8. Add enough of the pan juices to measure about 3 cups total. Blend until smooth.

9. Use immediately or pour into clean glass jars for storage.

Variations

• Herb Infused: Add fresh basil, oregano, or thyme to the blender for an herbaceous twist.

• Chunky Style: Blend only half the tomatoes and mix with the rest for a chunky texture.

• Smoky Flavor: Add a pinch of smoked paprika or roast with a halved red bell pepper.

• Sweet and Savory: Mix in a teaspoon of balsamic vinegar or a touch of maple syrup for depth.

• Extra Garlic: Roast whole garlic cloves in their skins along with the tomatoes and squeeze into the sauce.

• Spice Boost: Increase red pepper flakes or add a pinch of cayenne for more heat.

Storage/Reheating

Allow the sauce to cool completely before storing. Transfer to clean glass jars or airtight containers and refrigerate for up to 5 days. For longer storage, freeze in freezer-safe containers or silicone molds for up to 3 months. Thaw in the fridge overnight and reheat gently on the stovetop over medium-low heat until warmed through.
