This slow cooker 4-ingredient spinach mushroom ravioli is exactly the kind of dish my cousin brought to a family get-together and completely spoiled us with. It looks and tastes like something you’d order at a cozy Italian restaurant—plump cheese ravioli tucked into a rich, creamy mushroom and spinach sauce—but it comes together with almost no effort. Everything simmers away in the slow cooker while you live your life, and by the time you’re ready to eat, you’ve got a comforting, fancy-feeling dinner that’s totally weeknight-friendly.
Serve this creamy spinach mushroom ravioli in warm shallow bowls with plenty of sauce spooned over the top. A simple green salad with a bright vinaigrette helps cut through the richness, and a loaf of crusty bread or garlic breadsticks is perfect for soaking up the extra sauce. If you like a little something to sip, a crisp white wine like Pinot Grigio or a light red like Pinot Noir pairs nicely, but sparkling water with lemon is just as good. Finish the meal with fresh fruit or a light dessert to keep things from feeling too heavy.
Slow Cooker 4-Ingredient Spinach Mushroom Ravioli
Servings: 4

Ingredients
1 (24–26 ounce) jar creamy Alfredo sauce
1 pound frozen cheese ravioli (large square pasta pockets, not thawed)
8 ounces sliced baby bella (cremini) mushrooms
3 cups fresh baby spinach, loosely packed
Directions
Lightly coat the inside of your slow cooker with nonstick spray or a thin swipe of olive oil to help prevent sticking.
Pour about 1/2 cup of the Alfredo sauce into the bottom of the slow cooker and spread it around to create a thin, even layer.
Add roughly half of the frozen cheese ravioli in a single, mostly even layer over the sauce. It’s okay if some overlap slightly, but avoid stacking them too high in one spot so they cook evenly.
Scatter half of the sliced mushrooms over the ravioli, then add about half of the fresh baby spinach on top. The spinach will look like a lot, but it wilts down as it cooks.
Spoon or pour about half of the remaining Alfredo sauce evenly over the mushrooms and spinach, making sure to coat as much of the ravioli as possible to prevent dry spots.
Repeat the layers with the remaining ravioli, mushrooms, and spinach, then pour the rest of the Alfredo sauce over the top. Use the back of a spoon to gently nudge the sauce so it seeps between the pasta pockets and coats everything in a thick layer.
Cover the slow cooker with the lid and cook on LOW for 3 to 3 1/2 hours, or until the ravioli are tender and cooked through, the mushrooms are soft, and the spinach is wilted. Avoid lifting the lid during the first 2 hours so you don’t lose heat and moisture.
Once cooked, gently stir just enough to mix some of the mushrooms and spinach into the sauce while still keeping most of the ravioli intact. The sauce should look glossy, thick, and creamy, clinging to the large square ravioli pockets.
Taste the sauce and add salt and freshly ground black pepper if desired (the Alfredo may already be seasoned, so adjust carefully).
Serve the ravioli hot, spooning plenty of the creamy mushroom and spinach sauce over each portion. If you like, finish with a sprinkle of black pepper or a small handful of grated Parmesan right before serving.
Variations & Tips
For extra flavor without adding more ingredients, choose a high-quality Alfredo sauce with garlic or roasted garlic already in it. If you prefer a lighter feel, look for a light Alfredo sauce or use a refrigerated brand, which often tastes fresher. To make the dish feel even more like a restaurant meal, use a mix of mushrooms (baby bella plus a few shiitake or button mushrooms) as long as you keep the total to about 8 ounces. You can also swap the cheese ravioli for spinach and cheese ravioli for an extra hit of greens. If your slow cooker runs hot and you’re worried about overcooking, start checking the ravioli at the 2 1/2-hour mark; they should be tender but not falling apart. For meal prep, assemble the layers in the slow cooker insert the night before (keep the insert in the fridge), then pop it into the base and start cooking when you get home from work or on your lunch break. Leftovers reheat well in the microwave with a splash of milk or water to loosen the sauce, making this a great make-ahead option for busy weekdays.
