Why This Crockpot Vegetable Lasagna Is a Game-Changer

• Time-saving: Traditional lasagna can take over an hour to prep and bake. This method shaves time off while delivering the same rich, layered goodness.
• Hands-off cooking: After just 30 minutes of prep, your crockpot handles the rest, freeing you up to tackle your to-do list or relax.
• No stove or oven needed: Keep your kitchen cool and mess-free—no need to pre-boil noodles or monitor bubbling cheese.
• Customizable layers: Use whatever veggies you have on hand for endless variations. Mushrooms, zucchini, spinach—you name it!
• Meal-prep friendly: Make it ahead, store leftovers, and reheat for a quick midweek meal. This is lasagna that works as hard as you do.

Equipment You’ll Need for This Crockpot Vegetable Lasagna

Here’s what you need to whip up this easy slow cooker lasagna:

• 5-quart or larger slow cooker: The layers need space to cook evenly. Mine always turns out best in a round crockpot, but rectangular works too!
• Clean kitchen towel: This absorbs extra steam while the lasagna cooks, so your cheese stays perfectly gooey without getting watery.
• Mixing bowls: Use these to mix up the ricotta filling and prep your veggies.
• Grater: Freshly grated mozzarella and Parmesan bring that irresistible cheesy pull to every bite. Pre-shredded works in a pinch, but freshly grated melts better.

Simple Ingredients for Crockpot Vegetable Lasagna

You don’t need anything fancy for this healthy vegetable lasagna recipe. Here are some key ingredients and tips:

• Ricotta cheese: Creamy ricotta is the heart of any lasagna. For a lighter option, go for part-skim ricotta.
• Marinara sauce: A good-quality jarred marinara saves time. Look for one with no added sugar and rich tomato flavor.
• Vegetables: Zucchini, yellow squash, mushrooms, and spinach bring vibrant flavor and texture. Swap in bell peppers or kale if that’s what you have on hand.
• Lasagna noodles: No need to pre-cook! Regular lasagna noodles soften perfectly as they cook in the sauce and cheese.
