Ingredients
- 1 tablespoon olive oil
- 1 pound lean ground beef (93% lean)
- 2 clove garlic (minced)
- 1 teaspoon Italian seasoning (dried)
- 0.5 teaspoon salt
- 0.25 teaspoon black pepper (ground)
- 2 zucchinis (medium, sliced into 1/4-inch rounds)
- 1 jar marinara sauce (24 oz jar)
- 8 ounce shredded mozzarella cheese (part-skim)
- 0.5 cup Parmesan cheese (grated)
Instructions
- Preheat the oven to 400°F and lightly grease a 9x13-inch baking dish with nonstick spray.
- Heat olive oil in a large skillet over medium-high heat. Add lean ground beef, minced garlic, Italian seasoning, salt, and black pepper. Cook for 6 to 8 minutes, breaking meat apart with a spoon until fully browned and reaching an internal temperature of 160°F, then remove from heat.
- Spread 1/2 cup of marinara sauce across the bottom of the prepared baking dish. Arrange half of the sliced zucchini in an even layer over the sauce.
- Layer all of the cooked ground beef mixture over the zucchini, then pour the remaining marinara sauce evenly over the beef.
- Top with the remaining sliced zucchini, then evenly scatter shredded mozzarella cheese and grated Parmesan cheese over the top.
- Bake uncovered at 400°F for 20 to 25 minutes until the zucchini is fork-tender and the cheese is melted and golden brown around the edges. Let rest 5 minutes before slicing into 4 portions.
