Step-by-Step: Easy Cheesy Veggie Skillet Lasagna Recipe

Step 1: Sauté the Aromatics
In your cast-iron skillet, heat the olive oil over medium heat. Add the diced onion and cook until it becomes translucent, about 3-4 minutes. Then, add the minced garlic and cook for an additional minute until fragrant.
Step 2: Add the Veggies
Stir in the sliced mushrooms and diced zucchini. Sauté for about 5 minutes, or until the mushrooms have released their moisture and the zucchini is tender. Add the baby spinach leaves and cook until wilted. Season with salt and pepper to taste.
Step 3: Mix in the Sauce
Pour in the Italian tomato sauce, stirring everything together until well combined. Let the mixture simmer for a few minutes to allow the flavors to meld.
Step 4: Add the Noodles
Break the lasagna noodles into 3-4 inch pieces and add them to the skillet. Stir to ensure the noodles are submerged in the sauce.
Step 5: Layer the Cheese
Dollop the ricotta cheese over the top of the noodle mixture. Then sprinkle the shredded mozzarella and Parmesan cheese evenly across the top.
Step 6: Bake It Up
Preheat your oven to 375°F (190°C). Once preheated, transfer the skillet to the oven and bake for about 25-30 minutes, or until the cheese is bubbly and golden brown.
Step 7: Let It Rest
Once out of the oven, let the lasagna rest for about 5-10 minutes. This will help the layers set and make serving easier.
Step 8: Serve and Enjoy
Slice into your skillet lasagna, serve warm, and enjoy this cheesy, veggie-packed dish. Pair it with a side salad for a complete meal!
