Ingredients
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 1 small onion, finely chopped
- 28 ounces crushed tomatoes (no sugar added)
- 1 tablespoon tomato paste (no sugar added)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon red pepper flakes (optional)
- 1 teaspoon sea salt
- 1/2 teaspoon black pepper
- 1 teaspoon erythritol or preferred keto-friendly sweetener (optional)
- Fresh basil leaves for garnish (optional)
Equipment
- Medium-sized saucepan
- Sauté pan or skillet
- Wooden spoon or silicone spatula
- Knife and cutting board
- Measuring spoons
- Ladle (optional, for serving)
Instructions
- Heat the olive oil: Place a medium saucepan over medium heat and add 2 tablespoons of olive oil. Allow it to warm for about 1 minute.
- Sauté the aromatics: Add the minced garlic and chopped onion to the pan. Cook for 3-4 minutes, stirring frequently, until the onion becomes translucent and the garlic is fragrant. Be careful not to burn the garlic.
- Add crushed tomatoes and tomato paste: Pour in the 28 ounces of crushed tomatoes and stir in 1 tablespoon of tomato paste. Mix until fully combined.
- Season the sauce: Stir in the dried oregano, dried basil, red pepper flakes (if using), sea salt, and black pepper. If you prefer a slightly sweeter sauce, add 1 teaspoon of erythritol or your favorite keto-friendly sweetener.
- Simmer gently: Reduce the heat to low and let the sauce simmer uncovered for about 20-25 minutes. Stir occasionally to prevent sticking and allow the flavors to meld together.
- Adjust seasoning: Taste your sauce and adjust salt, pepper, or herbs as needed. If the sauce is too acidic, a little more sweetener can help balance it out.
- Finish and serve: Remove from heat. Garnish with fresh basil leaves if desired and serve immediately or let cool and store for later use.
Tips & Variations
“For a richer sauce, try adding a splash of heavy cream or a knob of butter at the end of cooking – just be sure it fits your keto macros!”
Here are some helpful tips to perfect your keto marinara sauce:
- Use quality canned tomatoes: Look for brands with no added sugar or preservatives for the best flavor and carb count.
- Fresh herbs: Swap dried oregano and basil for fresh herbs if you have them on hand. Add fresh basil at the end of cooking to preserve its bright flavor.
- Spice it up: Add a pinch of smoked paprika or Italian seasoning for a smoky depth.
- Chunky vs. smooth: If you prefer a smoother sauce, blend it with an immersion blender before simmering.
- Make it ahead: This sauce freezes well in portions. Defrost overnight in the fridge and reheat gently.
