  • Cutting board
  • Chef's knife
  • Large Stock Pot
  • Immersion Blender (Optional)


  • 2 tbsp olive oil
  • 1 medium yellow onion, finely diced
  • 4 ounces white mushrooms, diced
  • 1 green bell pepper, diced
  • 4 cloves garlic, peeled and minced
  • 1 carrot, diced
  • 8 ounces tomato paste, canned
  • 28 ounces crushed tomatoes, canned
  • 14.5 ounces tomato sauce, canned (plain)
  • 1 tbsp oregano
  • 1 tbsp basil
  • 2 tsp paprika
  • 1 tsp cayenne (more or less depending on how spicy you want it)
  • salt and pepper to taste


  • Heat olive oil in a large stock pot over medium-high heat.
  • When oil starts to shimmer, add the onion, bell pepper, mushrooms, and carrots. Cook the vegetable mixture for about 5 minutes or until they begin to soften.
  • After the vegetables start to soften, add the minced garlic and sautee for another 2 or 3 minutes, or until the garlic is fragrant.
  • When the veggies are very soft and fragrant, add 8 ounces of tomato paste to the mixture and stir until well incorporated.
  • Add the large can of crushed tomatoes and the can of tomato sauce and stir until everything is well mixed.
  • Turn the heat down to low, place the lid on your pot, and allow to simmer for 20 minutes.
  • After 20 minutes add paprika, cayenne, basil, and oregano, and let simmer for an additional 10 minutes.
  • As the final step, take a taste of your sauce and season with salt and pepper according to your tastes. I leave this step for last because I find that the amount of salt needed tends to vary based on how much water simmered out. You may not need as much as you think!
  • Serve hot on your favorite pasta dish or veggie pasta substitute!
  • Optional: If you want a smooth sauce rather than chunky, once it's finished is when you will blend with your immersion blender. I don't recommend a regular blender as it can create a lot of air bubbles and make your sauce orange.
