This zucchini lasagna is a low-carb, single serving dish made with thin slices of zucchini, a flavorful meat sauce, and layers of ricotta, mozzarella, and Parmesan cheese.
Slice the zucchini thinly lengthwise. Place on a cutting board, sprinkle with ¼ teaspoon salt, and let sit for 10 minutes. Pat dry with a paper towel.
In a skillet, heat olive oil over medium. Add onions and cook for 1 minute.
Stir in garlic and cook for 30 seconds.
Add ground beef, Italian seasoning, ¼ teaspoon salt, and pepper. Cook until no longer pink, stirring often.
Stir in ½ cup tomato sauce. Reduce heat and simmer for 3 minutes.
In a small bowl, mix ricotta with 2 tablespoons Parmesan.
To assemble, spread 3 tablespoons of sauce in a greased 5x5-inch baking dish. Add a layer of zucchini slices.
Top with half the meat sauce, half the ricotta mixture, and ¼ of the mozzarella.
Repeat with more zucchini, remaining meat sauce, remaining ricotta, and ¼ cup mozzarella.
If there's room, add one more layer of zucchini, top with the rest of the tomato sauce and remaining cheeses. If not, just add sauce and cheeses on top.
Bake at 350°F (177°C) for 30 minutes, or until the cheese is melted and bubbly.
Notes
Best Dish Size: A 5-inch square dish (22 ounces, 1.75 inches deep) fits one layer between zucchini slices.
