This 4-Ingredient Slow Cooker Holiday Manicotti is exactly the kind of recipe you want for a long weekend when the weather is beautiful and you would rather be outside than standing over the stove.

Ingredients
1. Prepared Marinara or Pasta Sauce — 24 to 26 ounces
Marinara sauce provides the moisture needed to cook the dry manicotti shells while also supplying most of the dish’s savory tomato flavor. Choose a sauce you genuinely enjoy because its flavor will carry throughout the entire recipe.
A smooth marinara works beautifully, but a chunky sauce can also be used if you prefer more texture.
2. Whole-Milk Ricotta Cheese — 15 to 16 ounces
Whole-milk ricotta forms the creamy heart of the manicotti. Its mild, slightly sweet flavor pairs naturally with tomato sauce and melted cheese.
For the richest texture, look for a creamy, basket-style whole-milk ricotta if available.
3. Shredded Italian-Blend or Mozzarella Cheese — 1 1/2 cups
The shredded cheese serves two purposes. Most of it is stirred into the ricotta filling for extra richness, while the remaining portion melts over the top for that irresistible golden, cheesy finish.
Mozzarella gives you a classic mild stretch, while an Italian blend can add more complexity.
4. Dry Manicotti Tubes — 12 to 14
The uncooked manicotti shells make this slow-cooker method especially convenient. There is no need to boil them first. Once surrounded by enough marinara sauce, they gradually soften as they cook.
Try to arrange them in a snug layer so the sauce can reach all sides of the pasta.
How to Make 4-Ingredient Slow Cooker Holiday Manicotti
Step 1: Prepare the Slow Cooker
Lightly coat the inside of a 5- to 6-quart slow cooker with nonstick spray or a thin layer of oil.
This helps minimize sticking and makes serving and cleanup easier.
Step 2: Add the First Layer of Sauce
Spread approximately 1/2 cup of marinara sauce across the bottom of the slow cooker.
This layer is important because it keeps the dry manicotti from sitting directly against the heated surface while giving the pasta moisture from underneath.
Step 3: Make the Ricotta Filling
In a medium bowl, combine the whole-milk ricotta with 1 cup of the shredded cheese.
Stir until the mixture is evenly combined.
There is no need for eggs or a long list of seasonings in this streamlined version. The ricotta provides the creamy filling while the marinara supplies the main seasoning and flavor.
Step 4: Fill the Manicotti
Transfer the ricotta mixture to a large zip-top bag.
Push the filling toward one corner, seal the bag, and carefully snip off a small section of the corner.
You now have a simple homemade piping bag.
Hold one dry manicotti tube over the bowl and gently pipe the ricotta mixture into one end. Turn the tube and continue filling from the opposite end until the filling reaches the center.
Do not overstuff the shells to the point that they split.
Repeat with the remaining manicotti.
Step 5: Arrange the Filled Shells
Place the filled manicotti in a single snug layer over the sauce.
If necessary, angle a few pieces slightly to make everything fit.
If your slow cooker is deep enough to require two layers, avoid creating a tall stack. Keeping the pasta relatively close to the sauce helps it cook more evenly.
Step 6: Cover Everything With Marinara
Pour the remaining marinara sauce evenly over the manicotti.
Make sure the shells are thoroughly coated. Pay special attention to any exposed areas of dry pasta because those areas need moisture to soften properly.
If needed, gently wiggle the slow cooker or use a spoon to work sauce into the spaces between the tubes.
Step 7: Slow Cook
Cover and cook on LOW for 3 1/2 to 4 1/2 hours.
The exact cooking time depends on your slow cooker and the particular manicotti shells you use.
The manicotti are ready when the pasta is very tender when pierced with a fork and the sauce is bubbling around the edges.
Avoid relying on appearance alone. Check a shell before deciding the dish is finished.
Step 8: Add the Remaining Cheese
Once the pasta is tender, sprinkle the remaining 1/2 cup shredded cheese evenly over the top.
Cover the slow cooker again and continue cooking on LOW for about 15 to 20 minutes, or until the cheese has completely melted and looks lightly bubbly.
Step 9: Rest Before Serving
Switch the slow cooker to WARM and allow the manicotti to rest for approximately 10 minutes.
This brief resting period helps the filling settle slightly and makes the manicotti easier to lift and serve without falling apart.
Spoon each serving onto a plate with plenty of the surrounding marinara sauce and melted cheese.
Pro Tips for Perfect Slow Cooker Manicotti
Don’t skip the sauce underneath
The first layer of marinara provides moisture and creates a protective barrier between the pasta and the heated bottom of the slow cooker.
Coat all exposed pasta
Dry spots are the enemy of evenly cooked manicotti. Make sure the sauce reaches as much of the pasta as possible before putting on the lid.
Use whole-milk ricotta
For the most luxurious filling, whole-milk ricotta is the way to go. Lower-fat versions can work, but the finished texture may be less creamy.
Don’t overfill the tubes
Pack the shells firmly enough to fill them, but avoid forcing in too much filling. A piping bag makes this process significantly easier and less messy.
Keep the lid closed
Every time you lift the slow-cooker lid, heat escapes. Keep the lid closed throughout most of the cooking process so the manicotti can cook efficiently.
Cook on LOW
For this recipe, LOW is preferable to WARM for cooking. The WARM setting is designed for holding already-cooked food, not for bringing a chilled, dairy-filled dish safely through cooking temperatures.
Check before serving
Cooking times vary between slow cookers. Before serving, test one manicotti for tenderness and make sure the center is thoroughly hot.
Easy Variations
Although this recipe is intentionally built around four ingredients, you can change the flavor simply by choosing different versions of those ingredients.
For a little heat, use a spicy arrabbiata-style marinara.
For a more herb-forward flavor, choose a basil marinara.
For a deeper cheesy flavor, substitute some of the mozzarella with provolone or smoked mozzarella.
If you prefer a lighter version, part-skim ricotta and reduced-fat shredded cheese can be used, although the finished manicotti will not be quite as rich.
What to Serve With Manicotti
Because this dish is rich and saucy, simple sides are the perfect match.
Serve your slow cooker manicotti with a crisp green salad dressed with a sharp vinaigrette. The acidity and fresh vegetables provide a refreshing contrast to the creamy filling and tomato sauce.
A basket of warm crusty bread or garlic toast is also practically mandatory for soaking up every last spoonful of marinara.
For a holiday-weekend gathering, add an easy antipasto platter with marinated vegetables, olives, and cured meats. Guests can snack while the manicotti stays warm in the slow cooker.
For drinks, sparkling water with lemon keeps the meal bright and refreshing, while a light fruity red wine can complement the tomato-rich sauce.
Food Safety and Storage
Keep the ricotta refrigerated until you are ready to prepare the filling, and avoid leaving filled manicotti sitting at room temperature for an extended period before cooking.
Use the LOW cooking setting, rather than WARM, to cook the dish.
Before serving, make sure the center of the manicotti is thoroughly hot and steaming.
Refrigerate leftovers promptly, ideally within 2 hours, and reheat leftovers thoroughly to 165°F. For best quality and safety, avoid repeatedly reheating the entire batch.
Frequently Asked Questions
Can I cook manicotti in a slow cooker without boiling the shells?
Yes. That is one of the biggest conveniences of this recipe. The dry manicotti shells gradually hydrate as they cook surrounded by marinara sauce.
Do I need to add water to the slow cooker?
Not normally. The marinara sauce provides the moisture needed to cook the pasta. Make sure the shells are well coated and surrounded by sauce.
Can I use mozzarella instead of Italian-blend cheese?
Absolutely. Shredded mozzarella works especially well and gives the dish a classic gooey cheese topping.
Can I prepare the manicotti ahead of time?
You can prepare the filling and have your ingredients ready ahead of time, but because the recipe contains refrigerated ricotta, avoid leaving assembled uncooked manicotti at room temperature. Refrigerate prepared components until you are ready to cook.
