  • 1 pound ground beef
  • 1/4 small onion, chopped
  • 3 garlic cloves, minced
  • 1 jar low carb spaghetti sauce ( I use either Rao’s or Mezzetta’s)
  • 1 cup Ricotta Cheese
  • 1 egg
  • 1/2 cup Parmesan Cheese
  • 3 cups Mozzarella Cheese
  • 2 cups zucchini, diced
  • 1 tablespoon butter
  • 1 tablespoon Italian Seasoning


  • Preheat oven to 350. 
  • Brown ground beef with chopped onion and minced garlic.
  • Drain.
  • Add ground beef back to the skillet and dump in the jar of spaghetti sauce. Simmer on low/medium heat covered for 10 minutes.
  • In a small bowl combine ricotta cheese, egg, and parmesan cheese.
  • Grease a 9X13 casserole dish. 
  • Before sauteing the zucchini, salt it just a bit and let it sit for approx 10 minutes to prevent the lasagna from being watery.
    In a small skillet, melt butter and saute zucchini for 3-5 minutes. Remove from skillet when it is still crisp and sit on paper towels so that some of the moisture drains out. 
  • Cover the bottom of the casserole dish with 1/2 of the spaghetti sauce.
  • Layer the sauteed zucchini next,
  • Spoon the ricotta cheese mixture in dollops on top of the zucchini. (see the picture in the post above) then use the back of a spoon to spread it out.
  • Layer 1/2 of the mozzarella cheese. 
  • Repeat the spaghetti sauce then end with mozzarella cheese. 
  • Sprinkle 1 tablespoon of Italian Seasoning on top.
  • Bake covered with aluminum foil for 20 minutes, then remove foil and bake for another 20 minutes. 
  • Serve and enjoy!
