Skillet Lasagna (Easy One-Pan Dinner)

This easy Skillet Lasagna recipe is a one-pan take on classic lasagna made with simple ingredients. A comforting, customizable dinner perfect for busy weeknights.

Craving lasagna but not the time, extra dishes, or long bake? This Skillet Lasagna recipe delivers all the cozy, familiar flavors of traditional lasagna in a fraction of the time—no layering required (using no-boil noodles!) Everything cooks together in one pan, making it ideal for busy weeknights when you want comfort food without the hassle.

I’ve been wanting to create a simplified take on lasagna for a while—one that taps into my Italian roots and the traditional flavors I hope get passed down for generations. While I may not have a secret family sauce recipe, using a good-quality store-bought marinara works beautifully here. With the addition of the other ingredients, this skillet version is anything but lacking in flavor and is easy to adapt for balanced eating by pairing protein, carbohydrates, and vegetables in one satisfying meal.

Ingredients: Skillet Lasagna

• No-Boil Lasagna noodles: I remember my mom growing up boiling the noodles to make lasagna and half the time the noodles breaking. These no-boil noodles will cook directly in the sauce, saving time while still giving the classic lasagna texture. My box came with 16 noodles, and I used half and saved the rest for the next time!
• Marinara Sauce: If I had the secret sauce recipe from the Lombardo side of my family, I would not share it. Sorry not sorry. Use your favorite store-bought sauce here to keep this recipe simple without sacrificing taste.
• Onion: Use the sweet Vidalia onions here for extra flavor. A small yellow onion will do as well.
• Garlic: Some say you don’t have to measure garlic, just use what your heart desires. The garlic adds depth and savory aroma.
• Red Pepper: Love adding as many vegetables to the lasagna as I can and red pepper adds some natural sweetness.
• Mushrooms: Add umami and a hearty, meat-like texture while boosting fiber and nutrients.
• Zucchini: Yes, more vegetables, more flavor!
• Ricotta cheese: Add creaminess and richness while helping balance the acidity of the sauce.
• Fresh mozzarella: Lasagna isn’t lasagna without mozzarella. Opt for skim-mozzarella to reduce the total saturated fat.
• Parmesan cheese: sharp and salty, the Parmesan will enhance the overall flavor and bring everything together.
• Basil, optional: Brightens the dish with a fresh, aromatic finish. Tastes even better if you use some from your garden outside!
• Olive Oil: You’re sauteing the vegetables at a medium heat, and olive oil helps provide the most flavor.
• Black Pepper: opting to omit salt here as the other components will contribute the sodium to the dish. Black pepper is nice to season the vegetables with as they sauté.

How To Make Skillet Lasagna

1. Heat olive oil in a large skillet over medium-high heat. Add the onion, bell pepper, zucchini, mushrooms, and black pepper and cook for 5-7 minutes, until the vegetables are softened. Stir in the garlic and sauté for another minute.
2. Break the lasagna noodles into large pieces and add them to the skillet.
3. Pour the marinara sauce over the noodles, gently pressing them down with a spoon to ensure they’re fully covered.
4. Reduce the heat to medium, cover, and cook for about 20 minutes, or until the noodles are tender.
5. Remove the lid and gently fold in the ricotta. Top with fresh mozzarella slices, cover again, and cook for 3-4 minutes, or until the cheeses melt.
6. Remove from heat and finish with Parmesan cheese and fresh basil. Serve warm.

Nutrition Highlights (Dietitian Tips)

• Plant-forward: Loaded with vegetables like mushrooms and zucchini for fiber, volume, and nutrients.
• Protein-rich (even without meat): I used a combination of cheeses for the protein. While the ricotta cheese does contribute some saturated fat, I opted for the leaner version of Mozzarella to scale back on the total saturated fat.
• Balanced carbs: Lasagna noodles provide energy, especially when paired with protein and fat for better balanced blood sugar levels.
• Calcium boost: Ricotta, mozzarella, and Parmesan add calcium for bone health.
• Customizable: Easy to increase protein or fiber depending on your needs.

Protein Note

While I intentionally kept this skillet lasagna meatless, it still delivers a solid protein punch thanks to the combination of ricotta, mozzarella, Parmesan, and pasta. For those who want to boost protein further, you can easily add lentils or another bean, —or serve it alongside a protein-rich side. This flexibility makes it a satisfying option whether you’re aiming for a vegetarian meal or a more traditional plate.

Easy Variations

• Vegetarian: Use lentils or another bean of choice. I tend to not utilize the plant-based alternatives but simply keep in mind the frequency with which you’re using those products and aim to opt for whole, plant-based options as much as possible.
• Extra veggie-packed: Stir in spinach toward the end. Yes, this dish is already loaded with vegetables, however, more vegetables lead to more flavor!

Final Thoughts

This skillet lasagna recipe is proof that dinner can be simple, satisfying, and weeknight friendly. With fewer dishes and big flavor, it’s an easy win when you want lasagna vibes without the traditional time commitment. The hardest part is cutting up all the vegetables (and that can be done ahead of time!) I hope you love this lasagna as much as I do! Reheats amazingly but did not freeze amazingly (because of all the vegetables/water content!)
