Ingredients You’ll Need
You don’t need anything fancy to pull this off—just a few simple ingredients you may already have in your kitchen:
- Zucchini (3 small): Acts as your lasagna “noodles.” Thinly sliced and pre-salted to draw out moisture.
- Ground beef (½ kg / about 1 lb): Choose 80/20 or leaner, depending on your preference.
- Yellow onions (2): Sautéed until golden to add depth of flavor.
- Canned diced tomatoes (1 can): Adds juiciness and tang. You can use fire-roasted for extra flavor.
- Shredded cheese: Go with mozzarella, cheddar, or a mix—whatever melts well and adds that gooey top layer.
- Spices: Salt, black pepper, granulated garlic, and smoked paprika. You can adjust the seasoning to taste.
Prepping the Zucchini Right 🥒
Zucchini has a lot of water, and if you skip this step, you might end up with a soggy mess. Here’s how to get it just right:
- Slice thinly: Use a mandoline slicer or a sharp knife to cut the zucchini lengthwise into thin strips.
- Salt generously: Sprinkle salt over the slices and let them sit for at least 15 minutes.
- Pat dry: After they release moisture, blot with paper towels to soak up as much liquid as possible.
This one extra step makes a huge difference in the final texture of your lasagna.
How to Build the Layers Like a Pro
This lasagna is all about layering the flavors. Here’s how to assemble it for maximum impact:
- Sauté onions: In a bit of olive oil, cook chopped onions until they’re soft and slightly caramelized.
- Add beef: Brown the ground beef with the onions. Season with garlic, paprika, salt, and pepper. Cook until moisture evaporates.
- Layer it up: In a greased baking dish:
- First layer: zucchini slices
- Second layer: seasoned beef mixture
- Repeat: another zucchini layer, then more meat
- Top with diced tomatoes and a generous handful of shredded cheese
- Bake: 40 minutes at 200°C (around 400°F) until the top is golden and bubbly.
Optional Add-Ins and Variations
Want to make it your own? Try these customization ideas:
- Add ricotta or cottage cheese between layers for a creamier texture.
- Throw in spinach or mushrooms to sneak in more veggies.
- Use Italian sausage instead of ground beef for spicier flavor.
- Top with fresh basil or parsley after baking for a burst of freshness.
- Swap cheeses: Try gouda, fontina, or even a spicy pepper jack for extra kick.
