Low-Carb Zucchini Lasagna (Keto Friendly)

This zucchini lasagna trims the carbs without trimming the comfort: thin roasted zucchini slices stand in for pasta, layering up with a rich, tomato-forward meat sauce and a creamy, bind-your-layers ricotta mixture. The success of this version rests on two simple moves—sweating and briefly roasting the zucchini to remove excess water, and folding a beaten egg into whole-milk ricotta so the filling sets like a custard rather than oozing out. The finished casserole has the familiar interplay of savory beef, tangy tomato, and molten mozzarella, but with a lighter mouthfeel and a vegetable-first texture you can actually taste.

This is a weeknight hero and a prep-ahead winner: it’s forgiving if you build it a few hours in advance, and it holds up well for leftovers. Use higher-fat ground beef (80/20) or a mix with Italian sausage for more depth; if you prefer milder flavors, swap the garlic for roasted shallot and add fresh basil between layers. The recipe is intentionally straightforward so home cooks can focus on proper moisture control and seasoning—two small details that make a big difference in zucchini-based bakes.
