I love how straightforward and wholesome the ingredients are in this recipe. Each one plays an essential role in building flavor, texture, or vibrant color that makes this lasagna stand out. From the fresh baby spinach for a pop of green and nutrition to the seasoned salt giving a little extra kick to the meat, these simple staples come together for something truly satisfying.

Olive oil cooking spray: Keeps the sheet pan non-stick and adds a subtle richness.
Olive oil (2 tbsp divided): Used for sautéing garlic and beef to build deep flavor.
Lasagna sheets (1 lb, broken into 2″ pieces): Short pasta pieces soak up sauce perfectly for easy layering.
Garlic (1 clove, chopped): Adds aromatic warmth that elevates the sauce.
Seasoned salt (1 tsp divided): I personally love Morton’s Season All for balanced seasoning of meat and greens.
Fresh baby spinach (6 oz, roughly chopped): Provides color, moisture, and a healthy green boost.
Whipped cottage cheese (1½ cups): Using full-fat gives the lasagna a luscious creaminess, almost like ricotta.
Ground beef (1 lb, 92% lean): Lean enough to be healthy but still juicy and flavorful.
Onion (½ cup diced): Adds subtle sweetness and texture to the sauce.
Marinara sauce (4½ cups): High-quality store-bought or homemade, it’s the heart of that classic tomato flavor.
Shredded low-fat mozzarella (2 cups divided): Melts beautifully and gives that cheesy stretch we all crave.
Grated Parmigiano Reggiano (1 cup divided): Adds a nutty, savory punch perfect for sprinkling on top.
Red pepper flakes and fresh chopped basil (optional): Great for a finishing touch with a pop of heat and brightness.

Directions

Step 1: Preheat your oven to 400 degrees Fahrenheit. Generously spray a 12 by 17-inch baking sheet with olive oil cooking spray. This ensures your lasagna won’t stick and helps develop a lovely crust on the cheese.

Step 2: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the chopped garlic and half a teaspoon of seasoned salt. Stir and cook for about one minute until the garlic smells fragrant—this is where the flavor base starts to build.

Step 3: Toss in the chopped spinach and cook it until just wilted, stirring frequently. Once done, transfer the spinach to a colander and press tightly to remove excess moisture (this step prevents a watery lasagna). Combine the pressed spinach with the whipped cottage cheese in a bowl and stir well to create a creamy filling. Set this mixture aside for later layering.

Step 4: If your skillet looks messy, wipe it clean and return to medium heat. Add the remaining tablespoon of olive oil. Then add the ground beef and diced onion. Cook, stirring occasionally, until the beef is no longer pink and just starting to brown—this usually takes about 8 to 10 minutes.

Step 5: Pour in the marinara sauce along with the remaining half teaspoon of seasoned salt. Allow this mixture to simmer on low heat for about 5 minutes. This step lets the flavors mingle and thickens the sauce slightly, which is exactly what you want for your lasagna.

Step 6: While the beef is cooking, bring a large pot of salted water to a boil. Add the broken lasagna sheets and cook them until al dente, roughly 10 minutes. Stir frequently to prevent the noodles from sticking to one another. Don’t overcook them—remember they’ll finish cooking in the oven. Drain and set aside.

Step 7: Place your drained lasagna noodles into a large bowl. Toss them with half a cup of mozzarella, half a cup of grated Parmigiano Reggiano, and the sauce-beef mixture from the skillet. Stir everything gently to coat the noodles evenly without breaking them apart too much.

Step 8: Spread the noodle mixture onto your prepared sheet pan in an even layer. Dollop the cottage cheese and spinach mixture evenly on top in spoonfuls. Then sprinkle with the remaining 1½ cups mozzarella and half cup Parmesan. I often add a little extra cheese here for maximum meltiness and flavor.

Step 9: Bake in your preheated oven for 25 to 30 minutes until the cheese is bubbly and golden brown on top. When it comes out, let it rest for about 5 minutes before slicing into squares—this resting time lets everything set wonderfully so it cuts cleanly.

Step 10: If you like, garnish with crushed red pepper flakes and a sprinkle of fresh Parmesan or chopped basil for that extra pop of color and flavor just before serving.

Servings and Timing

This recipe yields 8 generous servings, making it perfect for feeding a family or prepping for a few meals ahead. The prep time runs about 20 minutes, which is mostly hands-on cooking and tossing ingredients. The cooking time takes roughly 35 to 40 minutes including simmering and baking. In total, you’re looking at about 1 hour from start to finish, plus that 5-minute resting time after baking to let it set beautifully before slicing.

How to Serve This Sheet Pan High Protein Lasagna Recipe

A rectangular metal pan holds a baked lasagna with multiple layers visible at the edges. The bottom layer is made of pasta sheets with a tomato meat sauce that is reddish brown and slightly chunky. Above this is a thick creamy layer of melted mozzarella cheese which is golden and bubbly on top. There are many spoonfuls of creamy spinach ricotta cheese spread evenly in round dollops across the lasagna, their green leafy texture showing inside. The edges of the lasagna have slightly crisped pasta that is golden brown. The pan rests on a white marbled surface, and a black plastic spatula is on the left side, ready to serve.

When I’m ready to serve this lasagna, I like to keep the accompaniments simple so the main dish shines. A crisp green salad with a tangy vinaigrette is a natural pairing that cuts through the richness and adds freshness. I also love serving it alongside roasted vegetables or garlic bread for a more indulgent touch. The combination of crispy bread and cheesy, meaty lasagna is pure comfort food heaven in my book.

For presentation, I enjoy cutting the lasagna into neat squares straight from the baking sheet. I sometimes transfer slices onto warm plates and garnish each with a sprinkle of fresh basil leaves and a dash of those red pepper flakes to bring a beautiful color contrast and a hint of heat. This little extra effort always makes the meal feel special, whether it’s a casual family dinner or a weekend get-together with friends.

When it comes to drinks, I often reach for a medium-bodied red wine like Chianti or Sangiovese, which complements the tangy tomato sauce and rich cheeses perfectly. If I’m aiming for a non-alcoholic option, sparkling water with a splash of lemon or a light iced tea balances the robust flavors nicely. This recipe works beautifully for warm service, but I also admit the leftovers are surprisingly delicious at room temperature for a casual lunch or picnic.

Variations

I love experimenting with variations of this Sheet Pan High Protein Lasagna Recipe depending on what we have on hand or dietary needs. For instance, swapping out the ground beef with ground turkey or chicken adds a lighter protein option that still maintains great texture and flavor. If you’re vegetarian, simply replacing the meat with sautéed mushrooms, lentils, or a plant-based meat substitute works wonderfully and keeps that high protein count.

For those following gluten-free diets, I’m happy to report you can use gluten-free broken lasagna sheets or even substitute with thinly sliced zucchini or eggplant ribbons. These veggies add color and moisture with fewer carbs, making it a tasty alternative that still feels like classic lasagna. You could even try a vegan version by using plant-based ricotta and mozzarella alternatives and skipping the meat entirely, relying on hearty vegetables and robust marinara sauce to carry the dish.

If you want to change things up on the flavor front, adding Italian sausage or spicing up the marinara with extra herbs and crushed red pepper flakes brings a more intense taste punch. I’ve also played with swapping the spinach for kale or adding caramelized onions for a sweeter note. Even the cooking method can vary; while the sheet pan method is my favorite for ease, this mixture could be layered traditionally in a casserole dish if you prefer.

Storage and Reheating

Storing Leftovers

After enjoying your lasagna, store any leftovers in an airtight container and refrigerate within two hours to keep it fresh. I recommend a shallow glass or BPA-free plastic container so the lasagna cools quickly and stores evenly. Properly stored, leftovers stay delicious for up to 4 days, making them perfect for next-day meals or a quick lunch on the go.

Freezing

This lasagna freezes beautifully, which is one of my favorite ways to have a ready meal on hand. To freeze, let the lasagna cool completely, then portion it into airtight freezer-safe containers or wrap individual slices tightly in plastic wrap followed by foil. It will keep well for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the refrigerator before reheating.

Reheating

When reheating, I find it best to warm it gently in a preheated oven set to 350 degrees Fahrenheit for about 15-20 minutes. Covering it lightly with foil prevents the top from over-browning while ensuring it heats through evenly. Microwaving works for convenience, but I caution that it may make the texture a bit softer and the cheese lose some of its meltiness. Baking also helps restore that delightful bubbly crust and fresh oven-baked flavor.

FAQs

Can I use regular ricotta instead of whipped cottage cheese?

Absolutely! Whole milk ricotta is a fantastic substitute that adds creaminess and a rich texture to the spinach mixture. Just be sure to buy the full-fat or 2% version for the best flavor and consistency. If you use ricotta, you might want to stir it a bit to loosen it before combining with spinach.

Do I need to pre-cook the lasagna noodles before baking?

Yes, cooking the broken lasagna sheets until al dente is important. Because this recipe bakes for a relatively short amount of time, pre-cooking ensures that the noodles are tender but not mushy. It also helps the noodles to absorb the flavorful sauce evenly without drying out.

Is this recipe suitable for meal prep?

Definitely! This sheet pan lasagna holds up very well when refrigerated and rewarmed, making it great for meal prepping. You can cut it into portions, store them individually, and reheat as needed for quick lunches or dinners during a busy week.

Can I make this recipe vegan?

Yes, with some modifications! Use plant-based ground “meat” alternatives, a vegan marinara sauce, and dairy-free cheeses such as cashew ricotta or almond-based mozzarella-style shreds. Swap the cottage cheese mixture with blended tofu or a vegan ricotta alternative mixed with sautéed spinach for similar creaminess.

How spicy is this recipe? Can I adjust the heat?

The base recipe is mildly spiced, with just a pinch of seasoned salt and optional red pepper flakes for garnish. If you prefer more heat, feel free to add extra crushed red pepper flakes into the sauce or sprinkle on top before baking. You can control the spice level to suit your taste perfectly.
