This 4-ingredient slow cooker summer tortellini bake is my kind of weeknight cooking: minimal effort, big payoff, and a dinner that feels a little special despite how easy it is. We start with frozen cheese tortellini straight from the bag—no boiling—and let the slow cooker do the work with a bright tomato-basil sauce, a splash of creaminess from ricotta, and a blanket of melted mozzarella on top. While tortellini is traditionally boiled and sauced on the stovetop, this hands-off method turns it into a cozy baked-style pasta with barely any prep, perfect for hot Midwestern summers when you’d rather not turn on the oven.
Serve this tortellini bake with a simple green salad dressed in a light vinaigrette to balance the richness, and add some crusty bread or garlic toast for scooping up the saucy edges. A chilled glass of dry white wine, a light red, or sparkling water with lemon pairs nicely. For a heartier spread, set out a plate of raw summer veggies with hummus or a quick antipasto of olives and marinated peppers to echo the Italian flavors.
4-Ingredient Slow Cooker Summer Tortellini BakeServings: 4
Ingredients
1 (19–20 oz) bag frozen cheese tortellini (do not thaw)
1 (24 oz) jar tomato basil pasta sauce
1 cup ricotta cheese (whole milk preferred)
2 cups shredded mozzarella cheese
Directions
Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick cooking spray or a thin film of olive oil to help prevent sticking.
Pour about 1 cup of the tomato basil pasta sauce into the bottom of the slow cooker and spread it into an even layer. This creates a flavorful base and keeps the frozen tortellini from sticking.
Add the frozen cheese tortellini straight from the bag into the slow cooker, spreading them out in an even layer over the sauce. There is no need to thaw or pre-boil the pasta.
Dollop the ricotta cheese evenly over the tortellini in small spoonfuls, then gently spread or nudge it around so there are pockets of ricotta throughout the pasta rather than one large clump.
Pour the remaining tomato basil pasta sauce evenly over the top, making sure most of the tortellini are coated. If a few edges peek through, that’s fine—they’ll soften as they cook.
Cover the slow cooker and cook on LOW for 3 to 4 hours, or until the tortellini are tender but not falling apart. Avoid opening the lid during the first 2 hours so the temperature stays consistent and the pasta cooks evenly.
Once the tortellini are just tender, remove the lid and sprinkle the shredded mozzarella evenly over the top of the pasta.
Cover again and cook on LOW for another 10 to 15 minutes, just until the mozzarella is fully melted and gooey. If your slow cooker has a WARM setting, you can switch to WARM once the cheese is melted to hold the dish for up to 30 minutes.
Turn off the slow cooker. Let the tortellini bake rest, covered, for about 5 minutes to set slightly. Then scoop into bowls, making sure to dig down to get some of the saucy bottom, ricotta pockets, and stretchy mozzarella in each serving.
Variations & Tips
For a touch more summer brightness, stir a handful of fresh basil or chopped baby spinach into the slow cooker during the last 15 minutes of cooking, just before you add the mozzarella. You can also add a pinch of red pepper flakes or freshly ground black pepper to the sauce at the beginning for a gentle kick. If you’d like a meatier version, scatter about 1 cup of cooked crumbled Italian sausage or shredded rotisserie chicken over the frozen tortellini before adding the ricotta and sauce (be sure any meat is fully cooked and hot when added to keep it food-safe). For a lighter option, use part-skim ricotta and reduced-fat mozzarella; just know the texture will be slightly less rich. Food safety tips: Always start with the tortellini fully frozen and keep them refrigerated or frozen until you’re ready to cook to avoid any time in the temperature “danger zone.” Cook on LOW, not WARM, so the dish passes through the unsafe temperature range quickly. Avoid opening the slow cooker frequently, as heat loss can lengthen cooking time and keep the food at unsafe temperatures. Leftovers should be cooled promptly, transferred to shallow containers, and refrigerated within 2 hours; reheat until steaming hot before serving, and enjoy within 3 to 4 days.
