If you love the comfort of lasagna but want something lighter, this Cheesy Zucchini Ricotta Bake will hit the spot. Thinly sliced zucchini stands in for noodles, creamy ricotta and a bright marinara layer keep each bite super satisfying, and the whole thing is finished with bubbling mozzarella. It makes a cozy weeknight main or a beautiful addition to a weekend spread.

The first time I made this was after a trip to the farmers market when my zucchini haul was overflowing. Since then, my family asks for it every time zucchini season rolls around.

Ingredients

  • Medium zucchinis: Essential for the layers look for firm and unblemished skin
  • Olive oil: Helps roast the zucchini evenly use extra virgin for the best flavor
  • Salt and pepper: Enhances all the flavors use freshly ground pepper if possible
  • Whole milk ricotta cheese: Creamy and rich always check for a ricotta that lists milk and vinegar as top ingredients for freshness
  • Large egg: Binds the ricotta layer together for that classic lasagna-like texture
  • Grated Parmesan cheese: Adds cheesy depth and helps brown the top try to buy a wedge and grate it yourself
  • Garlic powder: Provides a subtle background flavor that melds with the creamy ricotta
  • Dried basil: Brings brightness and an Italian aroma go for a reputable brand for potency
  • Red pepper flakes: Optional but brings a touch of gentle heat
  • Marinara sauce: You want a tangy sauce with simple ingredients look for brands that avoid added sugar
  • Shredded mozzarella cheese: Melts into those classic stretchy layers whole milk is best for richness
  • Fresh basil leaves: Adds freshness and color for that final touch

Step-by-Step Instructions

Prep and Roast the Zucchini:
Slice the zucchinis into uniform quarter-inch rounds. Arrange these on a baking sheet and drizzle with olive oil. Season lightly with salt and pepper. Roast in a hot oven so the slices soften but do not go limp this prevents a watery bake.
Mix the Ricotta Filling:
In a medium bowl, blend ricotta with the egg, Parmesan, garlic powder, dried basil, and if you like a little spice, a pinch of red pepper flakes. Mix until creamy and fully combined. This mixture should be fluffy and fragrant.
Layer the Dish:
Spread a thin layer of marinara sauce on the bottom of your baking dish. Arrange half the roasted zucchini in a single layer, overlapping the edges slightly. Dot half the ricotta mixture over the top, spreading gently to cover. Drizzle more sauce, then sprinkle with a handful of shredded mozzarella. Repeat the layering one more time finishing with mozzarella.
Bake to Perfection:
Cover the dish with foil to keep everything moist and bake until the sauce is bubbling around the edges. Remove the foil for the last few minutes so the cheese can become golden and a bit crisp on top.
Rest and Garnish:
Let the bake rest about five minutes after pulling it from the oven. This makes the layers easier to slice and keeps everything intact. Add a shower of torn fresh basil just before serving for color and brightness.

My favorite part of this bake is how the roasted zucchini takes on a juicy almost buttery flavor under the bubbly cheese. Serving this to my folks last summer sparked conversation about old family recipes and new traditions we could blend together.

Storage Tips

Refrigerate any leftovers in a tightly sealed container. They will keep for up to three days. For quick lunches or dinners, simply reheat in the oven at a moderate temperature until warmed through. The bake also freezes well before or after baking but be sure to wrap tightly to prevent freezer burn. Thaw in the refrigerator overnight before reheating.

Ingredient Substitutions

Eggplant is an excellent substitute for zucchini especially if you catch a good sale or your garden is overflowing. For a tangier bake use part-skim ricotta or add a layer of sautéed spinach for extra greens. You can swap the mozzarella for fontina or provolone if you have either on hand.

Serving Suggestions

This bake is a meal on its own with a crisp green salad or a side of roasted vegetables. If you want to offer it as a side dish try pairing with grilled chicken or a simple lemony fish. A handful of toasted pine nuts sprinkled on top just before serving adds crunch and extra flavor.

Cultural Context

Zucchini ricotta bakes like this are modern spins on classic Italian and Italian American casseroles. Using sliced vegetables as a pasta substitute has long roots in southern Europe where cooks made do with what was freshest and affordable. In my kitchen it is a celebration of the summer harvest and a way to share familiar flavors with a healthy touch.
