Why This Slow Cooker Vegetable Lasagna is a Winner

A Flavorful Vegetable Medley

Feel free to customize the vegetable medley to your taste or what’s in season. The classic combo—zucchini, mushrooms, spinach, and bell pepper—provides a colorful array of flavors and nutrients. Sautéing the vegetables beforehand ensures depth of flavor and prevents excess moisture, so each layer holds together beautifully.

Layering for Success in the Slow Cooker

Start with a generous base of pasta sauce to prevent sticking, then alternate layers of uncooked lasagna noodles, creamy ricotta mixture, and your flavorful sautéed veggies. Top it all off with mozzarella for that iconic bubbly, golden finish. The slow cooker’s gentle heat allows the noodles to soften perfectly, absorbing the delicious sauces and juices from the vegetables.

Instructions

1. Heat olive oil in a skillet over medium heat. Sauté onion until softened, about 3 minutes. Add garlic, bell pepper, zucchini, and mushrooms; cook for 5–6 minutes, until vegetables are tender and most liquid has evaporated. Stir in spinach and Italian seasoning, then cook until spinach wilts, about 1 minute. Season with salt and pepper. Remove from heat.
2. In a medium bowl, mix ricotta cheese, egg, Parmesan, a pinch of salt, and pepper until smooth.
3. Spray the base and sides of your slow cooker with nonstick spray. Spread a thin layer of marinara sauce over the bottom.
4. Lay 2–3 lasagna noodles over the sauce, breaking as needed to fit. Top with one-third of the ricotta mixture, one-third of the sautéed vegetables, a handful of mozzarella, then more sauce. Repeat layers twice more, ending with remaining marinara and mozzarella.
5. Cover and cook on LOW for 4–5 hours, until noodles are tender and cheese is bubbling.
6. Let lasagna rest for 15 minutes before slicing. Sprinkle with fresh basil or parsley, if using. Serve warm and enjoy!
