With just ravioli, marinara sauce, and mozzarella cheese, you can create a bubbling, golden, oven-baked dish that tastes like you spent hours preparing it.

Why This 3-Ingredient Lasagna Works So Well
Traditional lasagna can be intimidating, requiring multiple components like homemade sauce, ricotta mixtures, béchamel, and careful layering. This simplified version cleverly replaces multiple layers with store-bought ravioli, which already contains pasta and filling in one neat package.
Here’s why this method is so effective:
- Ravioli replaces noodles and ricotta filling in one step
- Jarred marinara provides balanced flavor and moisture
- Mozzarella cheese creates the classic stretchy, golden top
- Baking melds everything together into a cohesive, hearty dish
The result is a lasagna-style casserole that feels familiar, comforting, and indulgent—without the usual prep work.
Ingredients Breakdown
Ravioli (1 lb / 450 g)
Spinach and ricotta ravioli are a popular choice because they closely resemble traditional lasagna filling. However, beef, chicken, mushroom, or cheese ravioli all work beautifully. Fresh or frozen ravioli can be used—no need to boil first.
Marinara Sauce (750 mL / 3 cups)
A good-quality jarred marinara is key since it provides most of the flavor. Choose one you enjoy on its own, whether it’s classic, garlic-forward, or herb-heavy.
Mozzarella Cheese (3 cups, grated)
Mozzarella gives the dish its signature melt and stretch. Pre-shredded works fine, but freshly grated mozzarella melts more smoothly.
Step-by-Step Method Explained
Step 1: Preheat the Oven
Set your oven to 450°F (230°C). A hot oven ensures the cheese melts properly and the sauce bubbles without drying out the pasta.
Step 2: Create the Base Layer
Spread ½ cup of marinara sauce across the bottom of a 9×13-inch baking dish. This prevents sticking and keeps the ravioli tender.
Step 3: First Layer
Sprinkle a small handful of mozzarella cheese over the sauce, then add a single layer of ravioli. Arrange them side by side with minimal gaps for even cooking.
Step 4: Repeat the Layers
Top the ravioli with about 1 cup of marinara sauce and another handful of cheese. Add a second layer of ravioli, followed by more sauce.
Step 5: Finish with Cheese
Top everything with the remaining mozzarella. This final layer creates the irresistible golden crust.
Step 6: Bake Covered
Cover the dish tightly with foil and bake for 30 minutes. This allows the ravioli to cook through and absorb the sauce.
Step 7: Bake Uncovered
Remove the foil and bake for another 10–15 minutes, until the cheese is bubbly, lightly browned, and the internal temperature reaches 165°F (74°C).
Step 8: Rest Before Serving
Let the lasagna rest for 5–10 minutes before slicing. This helps the layers set and makes serving easier.

Frequently Asked Questions (FAQs)
