Optional Add-Ins:

  • 1-1/2 - 2 cups spinach , chopped
  • 2 medium zucchini , peeled and chopped
  • 1/4 cup water , reserved as needed


  1. Spiralize zucchini using the ribbon blade or a vegetable peeler; set aside. Pat dry with a paper towel. (This step can be done up to 3 days in advance. Simply store zoodles in an airtight container with a paper towel to help absorb excess moisture.)

  2. Heat oil in a large skillet over medium-high heat, add in the ground protein and cook until browned, about 3-4 minutes, making sure to crumble and break down into small pieces as it cooks; drain any excess fat.

  3. Add the garlic and saute for 30 seconds to a minute or until fragrant. Add mushrooms and optional chopped zucchini, if using and saute for 4 minutes. Season with salt and pepper to taste.

    Add tomato paste, diced tomatoes, tomato sauce, oregano, red pepper flakes and 1 tablespoon of basil. Bring to a boil and reduce heat allowing to simmer. *Stir constantly until sauce begins to thicken (about 5 minutes).

    Add the ribboned zucchini noodles and cover with lid.

  4. After 1-2 minutes, remove the cover, swirl the zucchini around using tongs to avoid sticking to the pan. Continue cooking until zucchini is tender (another 2-4 minutes). If adding spinach, stir in after 3 minutes and cover again until spinach just wilted. **Remove pan from heat and stir in mozzarella and ricotta (or cottage cheese). Taste and adjust seasonings as needed.

Recipe Notes

*Add water as needed if the sauce is evaporating.

**If zucchini is letting out too much water, mix 2 teaspoons cornstarch with 2 teaspoon of cold water in a small cup. Add to the pan before adding the ricotta/cottage cheese. Bring to a boil to allow sauce to thicken up. Add ricotta/cottage cheese as directed above.
