Holiday Weekend Feast: Just 4 ingredients. I throw this together early so I can enjoy the beautiful May weather outside

You can keep this to four ingredients and still play a bit within those boundaries. Try a different jarred sauce—arrabbiata for a spicy kick, or a basil-heavy marinara for more herbal notes. Swap the Italian blend for smoked mozzarella or provolone if you like a deeper, almost wood-fired flavor. If you want extra richness while staying within the 4-ingredient concept, choose a ricotta that’s labeled whole-milk and “basket style”; it tends to be creamier and more flavorful. For a slightly lighter spin, use part-skim ricotta and a reduced-fat shredded cheese, but be aware the texture will be a bit less lush. If you have a smaller slow cooker, simply cook fewer manicotti tubes (and scale back the filling slightly) so they can sit in a single layer and hydrate properly. Food safety notes: Always keep the ricotta refrigerated until you’re ready to fill the manicotti, and avoid letting the filled tubes sit out at room temperature for long before they go into the slow cooker. Cook on the LOW setting, not WARM, to bring the dish safely through the temperature “danger zone” (40–140°F) in a reasonable time frame, and check that the center of the manicotti is hot and steaming before serving. Cool leftovers promptly, refrigerate within 2 hours, and reheat only once to at least 165°F for best quality and safety.
