This Zucchini Potato Meat Casserole begins by salting sliced zucchini and diced potatoes to draw out excess moisture, ensuring each layer remains tender rather than soggy. A robust filling of ground beef and pork, flavored with onion, garlic, grated carrot, and earthy spices—including Provencal herbs, red pepper, nutmeg, salt, and black pepper—is bound together by an egg and enriched with breadcrumbs for structure. Sautéed mushrooms add an umami boost, while a simple sauce of sour cream, mayonnaise, garlic, milk, and Parmesan melds into a silky binder. Layers of zucchini, meat filling, and potato are stacked in a foil-lined baking dish, then drizzled with olive oil and the creamy sauce. Covered in foil and baked at 170 °C, the casserole steams gently, melding flavors. Uncovered and sprinkled with grated cheese, a final blast at 180 °C produces a golden, bubbling crust. The result is a symphony of textures—from crisped cheese to melt-in-your-mouth vegetables—making this casserole a soul-warming centerpiece.

Step-by-step cooking directions
-
Preheat oven to 170 °C. Lightly grease a 22×22 cm baking dish and line with foil overhanging the edges.
-
Arrange zucchini slices in a single layer on a cutting board. Sprinkle ½ tsp salt evenly and let rest 5 minutes to draw moisture. Pat dry with paper towels.
-
In a bowl, toss diced potatoes with ¼ tsp salt, ¼ tsp Provencal herbs, and ¼ tsp red pepper. Set aside for later layering.
-
Heat a tablespoon of vegetable oil in a large skillet over medium heat. Sauté onions until soft and translucent, about 3 minutes. Add garlic and cook 30 seconds. Add mushrooms and cook 2 minutes until lightly browned. Transfer mixture to a bowl.
-
In the same skillet, add a splash more oil and brown ground meat, breaking into small pieces. Season with 1 ¼ tsp salt, ¼ tsp pepper, and ¼ tsp red pepper. Stir in grated carrot and cooked mushroom mixture; cook 2 minutes until carrot softens. Remove from heat.
-
In a large bowl, combine the meat mixture with beaten egg and 2 Tbsp breadcrumbs. Mix until well incorporated.
-
To prepare sauce, whisk together sour cream, mayonnaise, minced garlic, nutmeg, and milk in a small bowl until smooth. Stir in 70 g Parmesan and season with salt and pepper.
-
Layering: Spread half the zucchini slices on the bottom of the prepared dish. Top with half the meat mixture, pressing gently. Arrange seasoned potatoes evenly over meat, then cover with remaining meat mixture. Finish with the remaining zucchini slices. Drizzle the creamy Parmesan sauce over the top, ensuring it seeps into the layers.
-
Cover tightly with foil, sealing the edges. Bake covered for 50 minutes until potatoes are tender when pierced.
-
Carefully remove foil, sprinkle grated cheddar or mozzarella evenly. Increase oven temperature to 180 °C and bake uncovered 10–15 minutes until cheese is golden and bubbly.
-
Remove from oven and let rest 10 minutes before slicing to allow layers to set.

Pair with a simple green salad dressed in lemon vinaigrette to cut richness. Offer crusty bread to soak up sauce. Serve with steamed broccoli or roasted Brussels sprouts.
