This is spinach-ricotta manicotti made with no-boil lasagna sheets softened in hot water — a straightforward swap that cuts prep time without changing how the finished dish tastes or feels. The filling is ricotta and well-drained spinach, seasoned with lemon zest and a pinch of nutmeg, baked under a quick San Marzano marinara with melted cheese on top. If you need a hot, filling pasta dinner on the table in about 30 minutes, this is a reliable way to get there.
Why this recipe works
Two things actually drive the results here. First, soaking no-boil lasagna sheets in hot water for a few minutes makes them pliable enough to roll without cracking — you get a proper tube shape without boiling a pot of water or handling fragile fresh pasta. Second, draining the spinach thoroughly before mixing it into the ricotta keeps the filling from turning watery in the oven; a soggy filling is the most common reason manicotti disappoints, and squeezing out the liquid upfront solves it completely. The 450°F bake with foil on first, then a short broil at the end, handles the rest — the covered phase heats the filling through evenly, and the broiler gives you browned cheese on top without drying out the pasta underneath.
Keeping and reheating
Leftovers keep well covered in the fridge for up to 4 days. Reheat individual portions in the microwave with a splash of water added to the dish and a loose cover over the top — 2 to 3 minutes on medium power works better than high heat, which toughens the pasta. For larger portions, cover the baking dish with foil and reheat in a 350°F oven for about 20 minutes. This manicotti also freezes well before baking: assemble the whole dish, wrap it tightly, and freeze for up to 2 months. Bake straight from frozen, covered, at 375°F for 45 to 50 minutes, then uncover for the last 5 minutes to brown the cheese.
Common problems and fixes
- Noodles tear when rolling: They need more soaking time. If a sheet cracks when you try to bend it, put it back in the hot water for another 2 minutes. Sheets that are only slightly softened will split under pressure.
- Filling leaks out during baking: The rolls are probably too loosely packed or the seam is face-up. Place each roll seam-side down in the sauce — the weight of the filling holds it closed as it bakes.
- Cheese topping burns before the filling is hot: Your oven runs hot, or the broiler is too close. Keep the rack in the center position and watch the broiler step — 2 minutes is a guideline, not a guarantee. Pull it when the cheese is spotted and bubbling.
- Filling tastes bland: Under-seasoned ricotta is the usual cause. Taste the filling before you roll anything and adjust salt. Ricotta absorbs seasoning less than you expect, so it needs a little more than seems right.
- Watery sauce pooling at the bottom of the dish: The spinach was not drained well enough, or the marinara was too thin. Squeeze the spinach until almost no liquid comes out — skip the garnish on top of the sauce and focus the effort here, it matters far more.
30-Minute Spinach-Ricotta Manicotti with Quick San Marzano Marinara
Equipment
- 13x9-inch baking dish
- Medium saucepan
- Large mixing bowl
- Fine-mesh strainer or clean kitchen towel (for spinach)
- Measuring cups and spoons
- Whisk or spatula
- Chef’s knife and cutting board
- Microplane or fine grater
- Piping bag or zip-top bag (for filling)
- Tongs
- Aluminum Foil
- Ladle
Ingredients
For the Quick Marinara:
- 2 tbsp extra-virgin olive oil fruity, good-quality
- 3 cloves garlic finely minced
- ¼ tsp crushed red pepper flakes optional, for gentle heat
- 28 oz crushed San Marzano tomatoes from 1 can; I like Mutti or Cento
- 1 tsp kosher salt Diamond Crystal; reduce to 3/4 tsp if using Morton
- ½ tsp granulated sugar optional, to balance acidity
- 6 leaves fresh basil torn by hand
For the Ricotta–Spinach Filling:
- 1 ½ cups whole-milk ricotta drain if very wet; BelGioioso or Calabro
- 1 cup frozen chopped spinach thawed and squeezed very dry (about 5 oz)
- 1 large egg lightly beaten
- ½ cup Parmigiano-Reggiano finely grated, plus extra for serving
- 1 cup low-moisture mozzarella shredded; part of total cheese
- 1 tsp lemon zest finely grated
- ¾ tsp kosher salt Diamond Crystal; reduce slightly if using Morton
- ½ tsp freshly ground black pepper
- 1 pinch ground nutmeg freshly grated if possible
For Assembly:
- 12 pieces no-boil lasagna sheets Barilla Oven-Ready; softened in hot water to roll into manicotti
- ½ cup low-moisture mozzarella shredded, for topping
- 1 tbsp extra-virgin olive oil for greasing and finishing drizzle
- 2 tbsp fresh basil and/or flat-leaf parsley chopped, for garnish
Instructions
- Heat the Oven and Prep the Dish (1 minute): Preheat the oven to 450°F (232°C). Lightly grease a 13x9-inch baking dish with a little olive oil to prevent sticking.
- Soften the Pasta Sheets (10 minutes, mostly hands-off): Slide the no-boil lasagna sheets into a shallow pan of very hot tap water. Soak 10 minutes, flipping once, until pliable and bendable without cracking.Sensory Cue: Sheets will feel silky and flexible.Tip: Fan the sheets slightly so they don’t overlap and stick.Alternative: If using traditional manicotti tubes, parboil in salted boiling water for 5–6 minutes until just pliable; drain and cool on an oiled tray.
- Make the Quick Marinara (8 minutes): In a medium saucepan, warm 2 tbsp olive oil over medium heat until shimmering. Add garlic and red pepper flakes; sauté 45–60 seconds until fragrant but not browned. Stir in crushed tomatoes, salt, and sugar. Simmer briskly for 8 minutes, stirring occasionally, until slightly thickened and bright. Off heat, stir in torn basil.Aroma Cue: Sweet tomato, gentle garlic, and fresh basil.
- Mix the Filling (3–4 minutes): In a large bowl, combine ricotta, well-dried spinach, egg, Parmigiano-Reggiano, 1 cup mozzarella, lemon zest, salt, pepper, and nutmeg. Stir until creamy and cohesive.Texture Cue: Smooth, spoonable, not runny. Transfer to a piping bag or a zip-top bag (snip a 3/4-inch corner).
- Sauce the Base and Fill (5 minutes): Ladle about 1 cup of marinara into the prepared baking dish and spread to coat. Lay a softened pasta sheet on your board. Pipe a generous line of filling (about 3 tbsp) along one short edge, then roll into a neat tube. Place seam-side down in the dish. Repeat to make 12 manicotti. Spoon the remaining sauce over the top. Sprinkle with the remaining 1/2 cup mozzarella and a dusting of extra Parm if you like.
- Bake, then Broil (10 minutes total): Cover the dish tightly with foil and bake at 450°F (232°C) for 8 minutes, until the sauce bubbles at the edges and the centers read at least 165°F (74°C). Remove the foil and broil on High (about 500°F/260°C) for 2 minutes to blister and lightly brown the cheese. Rest 3 minutes to set.
- Finish and Serve (1–2 minutes): Drizzle with a thread of olive oil and scatter chopped basil/parsley. Listen for a gentle sizzle; the cheese should be glossy with browned freckles.
Notes
Lisa’s Tips:Â
- Ricotta Perfection: If ricotta seems wet, drain it in a fine-mesh strainer for 10–15 minutes for a richer, less watery filling.
- Texture Boost: Fold 1/4 cup finely diced low-moisture mozzarella into the filling for pockets of gooey stretch.
- Crespelle Option: Swap pasta for 10–12 store-bought crepes; skip soaking and go straight to filling and baking.
- Herb Swap: Use oregano instead of basil for a more robust, pizzeria-style sauce.
- Dietary Notes: Gluten-free oven-ready lasagna sheets work well. For vegetarian rennet, choose a verified Parm-style cheese.
- Cottage Cheese Swap: Blend cottage cheese 30 seconds until silky, then use in place of ricotta for extra protein.
- Professional Note: To accelerate browning without drying, keep the dish covered until the last 2 minutes. If your broiler runs very hot, crack the oven door and watch closely—cheese should blister, not burn.
Serving Suggestions:Â
- Plate 2–3 manicotti over a warm spoonful of marinara. Finish with basil chiffonade, a whisper of grated Parm, and a final olive oil gloss.
- Color Cues: Ruby-red sauce, bright green herbs, and caramelized golden patches of cheese.
- Pair with a simple arugula salad with lemon and olive oil, and a glass of Chianti Classico or a sparkling water with a lemon twist.

FAQ
Can I use frozen spinach instead of fresh?
Yes, frozen spinach works well here and is actually easier to drain thoroughly. Thaw it completely, then squeeze out as much liquid as possible with your hands or a clean kitchen towel before adding it to the ricotta.
My kids don’t like visible spinach — can I hide it better?
Chop the thawed or cooked spinach very finely before mixing it in. Finely chopped spinach blends into the white ricotta filling much more completely, and the flavor is mild enough that most picky eaters won’t notice it.
Can I assemble this earlier in the day and bake it later?
Yes, you can assemble the dish up to 8 hours ahead and refrigerate it covered. Add 5 to 7 minutes to the covered baking time since you’re starting from cold rather than room temperature.
What can I use if I don’t have a piping bag or zip-top bag for the filling?
A regular spoon works fine — it just takes a little more patience. Lay the softened noodle flat, spoon a line of filling down the center, and roll it up; the filling doesn’t need to be perfectly even to bake well.
