Ingredients

• 3 tablespoons Olive oil
• 4 cloves Garlic cloves, minced
• 1 medium Yellow onion, finely chopped
• 1 medium Zucchini, finely diced
• 1 medium Red bell pepper, finely diced
• 1 cup Cremini mushrooms, finely chopped
• 1 28-ounce can Crushed tomatoes (no sugar added)
• 2 tablespoons Tomato paste (no sugar added)
• 1 teaspoon Dried basil
• 1 teaspoon Dried oregano
• 0.25 teaspoon Crushed red pepper flakes
• 0.5 teaspoon Salt
• 0.5 teaspoon Black pepper
• 2 tablespoons Fresh parsley, chopped
• 2 tablespoons Fresh basil, chopped

Directions

Step 1

Heat the olive oil in a large saucepan over medium heat.

Step 2

Add the minced garlic and chopped onion. Sauté for 3-4 minutes until the onion becomes translucent and aromatic.

Step 3

Stir in the diced zucchini, red bell pepper, and chopped mushrooms. Cook for 5-7 minutes, stirring occasionally, until the vegetables are softened.

Step 4

Add the crushed tomatoes and tomato paste to the saucepan. Stir to combine well.

Step 5

Season with dried basil, oregano, crushed red pepper flakes, salt, and black pepper. Stir to incorporate the seasonings throughout the sauce.

Step 6

Reduce the heat to low and let the sauce simmer uncovered for 30 minutes, stirring occasionally. This allows the flavors to meld and the sauce to thicken.

Step 7

Taste and adjust seasoning if necessary. If you prefer a smoother sauce, use an immersion blender to blend it to your desired consistency.

Step 8

Stir in the fresh parsley and basil just before serving for a burst of freshness.

Step 9

Serve hot over zoodles, grilled chicken, or any keto-friendly dish of your choice.
