No-boil manicotti recipe lets dry pasta tubes soften directly in a covered baking dish, so there is no pot of water to boil and no delicate cooked shells to tear. The key is simple: use enough thinned marinara to completely surround the pasta, cover the dish tightly, and bake until the tubes are tender.
This version has a creamy three-cheese filling, a generous tomato sauce, and a lightly browned mozzarella top. It serves 6 to 7.
Prep time: 25 minutes
Bake time: 60 to 70 minutes
Total time: About 1 hour 30 minutes
Yield: 14 manicotti
Ingredients
For the filling
- 15 ounces whole-milk ricotta
- 1 ½ cups shredded low-moisture mozzarella, divided
- ½ cup finely grated Parmesan, divided
- 1 large egg
- 2 tablespoons finely chopped parsley
- 1 teaspoon dried Italian seasoning
- ½ teaspoon garlic powder
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
For the pasta and sauce
- 14 dry manicotti tubes, about 8 ounces
- 48 ounces marinara sauce
- 1 ½ cups water
- 1 tablespoon olive oil, for the baking dish
Why No-Boil Manicotti Works
Dry manicotti absorbs liquid while it bakes. Marinara provides flavor, while the added water supplies enough moisture for the pasta to hydrate. A tightly sealed foil cover traps steam and prevents the exposed edges from becoming tough.
Do not use a shallow layer of thick sauce. Every pasta tube should be covered with the thinned sauce before baking.
How to Make No-Boil Manicotti
- Heat the oven to 350°F. Lightly oil a 9-by-13-inch baking dish.
- Stir the marinara and water together in a bowl. Spread 1 ½ cups of the sauce mixture across the bottom of the dish.
- In a separate bowl, mix the ricotta, 1 cup mozzarella, ¼ cup Parmesan, egg, parsley, Italian seasoning, garlic powder, salt, and pepper until evenly combined.
- Transfer the filling to a piping bag or a large zip-top bag with one corner snipped off. Pipe filling into both ends of each dry manicotti tube. Filling from both sides avoids air gaps and helps keep the tubes from splitting.
- Arrange the filled tubes in one layer over the sauce. Pour the remaining sauce mixture over them, turning any uncovered edges under the sauce with a spoon.
- Cover the dish tightly with foil. Bake for 55 minutes.
- Carefully remove the foil and test one tube with the tip of a small knife. It should slide through the pasta without resistance. If needed, re-cover and bake for another 10 to 15 minutes.
- Sprinkle with the remaining mozzarella and Parmesan. Bake uncovered for 8 to 10 minutes, until the cheese melts and begins to brown at the edges.
- Rest for 10 minutes before serving. This gives the filling time to set and makes the manicotti easier to lift from the dish.
The Most Important Tips for Tender Pasta
- Use regular dry manicotti tubes. Pasta thickness varies by brand, so check tenderness instead of relying only on the clock.
- Keep the pasta fully covered in sauce. Exposed sections can stay firm.
- Seal the foil tightly around the baking dish. Steam is part of the cooking process.
- Do not reduce the water. The sauce may look loose before baking, but the pasta absorbs much of it.
- Use a piping bag rather than a spoon if possible. Dry tubes are sturdy and easy to fill neatly.
For a spinach version, finely chopped spinach must be squeezed very dry before it goes into the cheese mixture. The same principle makes spinach and ricotta manicotti creamy rather than watery.
Make-Ahead and Storage
Assemble the manicotti up to one day ahead, cover tightly, and refrigerate. Bake it directly from the refrigerator, adding about 10 minutes before checking for tender pasta.
Refrigerate leftovers in a covered container for up to 4 days. Reheat covered portions at 350°F until hot throughout, adding a spoonful of marinara if the pasta looks dry.
For freezing, assemble the dish in a freezer-safe pan, cover it tightly, and freeze before baking. Thaw overnight in the refrigerator, then bake as directed. This gives the pasta the most dependable texture.
Easy Variations
Add spinach
Mix 10 ounces of thawed, thoroughly squeezed frozen spinach into the filling. Add an extra tablespoon of Parmesan to keep the flavor balanced.
Add meat sauce
Brown 1 pound of Italian sausage, ground beef, or turkey. Drain excess fat, then stir it into the marinara before adding the water. The pasta still needs the full amount of liquid.
Use cottage cheese
Cottage cheese can replace ricotta for a lighter, slightly tangier filling. Blend it briefly for a smoother texture if preferred.
Change the sauce
Marinara is the easiest choice because it has enough acidity to balance the cheese. For other options, see these sauces that pair well with manicotti; creamier sauces may need a lighter hand so the dish does not become overly rich.
Frequently Asked Questions
Do you have to boil manicotti before baking?
No. Dry manicotti can bake without precooking when it is completely covered in thinned sauce and the dish is sealed tightly with foil.
Why is my no-boil manicotti still hard?
The usual causes are not enough liquid, sauce that did not cover the pasta, or loose foil that allowed steam to escape. Add a little hot water around the firm tubes, cover tightly, and return the dish to the oven.
Can I use jarred sauce?
Yes. A good jarred marinara works well. Mix it with water before assembling so the pasta has enough moisture to soften.
Can no-boil manicotti be made without egg?
Yes. The filling will be slightly softer, but it will still bake well. Add 2 extra tablespoons of Parmesan to help it hold together.
How do I know when manicotti is done?
The pasta should be tender when pierced with a knife, and the center of the filling should be hot. If the tube still feels firm or chalky, cover the pan again and bake longer.
