  • 2 pounds lean ground beef
  • 1 pound Italian sausage
  • 1 small onion, chopped
  • 3 cloves garlic, minced
  • 1 (14.5-ounce) can diced tomatoes
  • 3 (6-ounce) cans tomato paste
  • 1 1/2 teaspoons Italian seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon red pepper flakes
  • 4 zucchini, sliced lengthwise into 1/8-inch thick pieces
  • salt
  • Olive oil
  • 1 (15-ounce) container ricotta cheese
  • 1 egg
  • 2 cups shredded mozzarella, divided
  • 1/4 cup grated Parmesan cheese


  • In a large pan, brown ground beef and Italian sausage, crumbling it with a wooden spoon. Once most of pink is gone, add onion. Continue to cook for 2 to 3 minutes to soften the onion some. Add garlic and cook 1 more minute. Drain off any excess liquid/fat.
  • Add diced tomatoes and tomato paste. Stir well to combine.
  • Mix in Italian seasoning, salt, and red pepper flakes.
  • Sprinkle zucchini lightly with salt and let sit for 10 minutes. This will draw some of the moisture out of the zucchini and help prevent the lasagna from being runny and liquidy. Blot zucchini with paper towels.
  • Heat a grill pan or large skillet over medium-high heat and coat it with olive oil. Cook zucchini for just a minute or 2 per side to soften. No need to completely soften the zucchini, you just want to get the cooking process started.
  • Preheat oven to 350 degrees and coat a 9X13-inch pan with cooking spray.
  • In a bowl, mix together ricotta cheese, egg, 1/2 cup mozzarella, and Parmesan cheese.
  • Place 1/3 of zucchini slices on bottom of casserole dish as you would lasagna noodles.
  • Top zucchini with 1/3 of meat mixture and 1/2 of cheese mixture.
  • Do another layer of zucchini, sauce, and cheese.
  • Place the third and final layer of zucchini and top with remaining sauce. Cover with the remaining 1 1/2 cups shredded mozzarella cheese.
  • Place baking pan on a baking sheet and place in oven for 30 minutes. Let cool for 15 minutes before slicing.
