Ingredients

Ingredient Quantity
Olive oil 2 tablespoons
Yellow onion, finely chopped 1 medium
Garlic cloves, minced 4
Red bell pepper, diced 1 medium
Carrot, grated 1 medium
Canned crushed tomatoes 28 ounces (1 can)
Tomato paste 2 tablespoons
Dried oregano 1 teaspoon
Dried basil 1 teaspoon
Salt to taste (about 1 teaspoon)
Black pepper, freshly ground ½ teaspoon
Red pepper flakes (optional for heat) ¼ teaspoon
Fresh basil leaves, chopped (for garnish) ¼ cup
Water or vegetable broth (to thin sauce if needed) ¼ cup

Equipment

  • Large skillet or saucepan
  • Wooden spoon or silicone spatula
  • Chef’s knife
  • Cutting board
  • Measuring spoons
  • Grater (for carrot)
  • Ladle or serving spoon
  • Optional: Blender or immersion blender (for smoother sauce)

Instructions

  1. Heat the olive oil in a large skillet or saucepan over medium heat. Once hot, add the finely chopped yellow onion. Sauté for about 5 minutes until the onion becomes translucent and soft, stirring occasionally.
  2. Add the minced garlic and cook for another 1-2 minutes until fragrant. Be careful not to burn the garlic as it can turn bitter.
  3. Stir in the diced red bell pepper and grated carrot. Cook for about 5 minutes, stirring occasionally, until the vegetables soften. These add natural sweetness and depth to the sauce.
  4. Add the canned crushed tomatoes and tomato paste to the pan. Mix well to combine all ingredients. Tomato paste intensifies the tomato flavor and thickens the sauce.
  5. Season the sauce with dried oregano, dried basil, salt, black pepper, and optional red pepper flakes for a touch of heat. Stir everything together thoroughly.
  6. Reduce the heat to low and let the sauce simmer gently for 20-30 minutes, uncovered. Stir occasionally to prevent sticking. This allows the flavors to meld beautifully.
  7. If the sauce becomes too thick, add water or vegetable broth a little at a time until you reach your desired consistency.
  8. Taste and adjust seasoning as needed. If you prefer a smoother sauce, use an immersion blender directly in the pan or transfer to a blender and pulse until smooth.
  9. Remove from heat and stir in fresh chopped basil just before serving for a fresh, aromatic finish.

Tips & Variations

Tip: For an extra layer of flavor, roast your red bell pepper before adding it to the sauce. This adds a smoky sweetness that enhances the overall taste.

Variation: Want a creamy texture? Try mixing in some Vegan Bechamel Sauce after simmering for a luscious, velvety pasta experience.

Substitution: No canned tomatoes? Use fresh, ripe tomatoes (about 6 medium), peeled and chopped, but extend cooking time to allow the sauce to thicken properly.

You can also add chopped mushrooms or zucchini to the sauce for more texture and nutrients. For a spicy kick, increase the red pepper flakes or add a dash of smoked paprika.

This sauce freezes well, so double the batch and save some for busy nights.
