Jumbo pasta shells filled with a pumpkin and ricotta mixture seasoned with sage and nutmeg, baked in marinara under mozzarella and Parmesan.
Twenty minutes of filling shells, thirty-five in the oven, and a five-minute rest. Six servings from one dish.
Why This Recipe Works
- One egg binds fifteen ounces of ricotta and a cup of pumpkin into a filling that holds its shape when a shell is cut. Without it the mixture slumps out of the shell as soon as it heats.
- The garlic is cooked for thirty seconds in oil and cooled before it joins the filling. Raw minced garlic in a ricotta mixture stays sharp through the bake; thirty seconds is enough to take that edge off without browning it.
- Whole-milk ricotta, not part-skim. Lower-fat ricotta releases water as it bakes and thins the marinara underneath into something loose.
- Nutmeg at a quarter teaspoon is small enough to be invisible and large enough to matter. It is the traditional partner to both ricotta and squash, and it is what makes the filling taste finished rather than merely orange.
- Covered then uncovered is two different jobs: the covered phase drives heat into the filling, the uncovered phase browns the cheese and thickens the sauce. Doing it all uncovered gives a browned top over an underheated middle.
Loading The Dish, In Order
Steps 4 through 6 build the dish in four passes, and both the mozzarella and the Parmesan are deliberately split between the filling and the top. Getting the order right is what stops the shells drying out at the edges.
One cup of marinara, on the base
Half the sauce goes down first, spread across the bottom of the 9-by-13. This is not decoration — it is the moisture that keeps the underside of each shell from baking onto the dish.
Twenty filled shells
Pumpkin, ricotta, egg, half a cup of the mozzarella, a quarter cup of the Parmesan, the cooked garlic, sage, nutmeg, salt and pepper, mixed and spooned in. Arrange them open side up in one layer so the filling stays put.
The remaining marinara
Spooned around the shells and only lightly over them. Around, mostly: burying the shells means the filling steams rather than setting, and the tops lose their browning.
The reserved cheese
The other half cup of mozzarella and quarter cup of Parmesan over the top. Held back for exactly this — cheese mixed into the filling browns nowhere.
Covered for 25 minutes so everything heats through, then uncovered for 10 so the top browns and the sauce reduces. Five minutes of rest before serving lets the filling firm enough to lift a shell whole.
Ingredient Notes
- Jumbo pasta shells
- Twenty of them, and it is worth boiling a few extra: shells split in the pot more often than any other shape, and a torn one cannot be filled.
- Whole-milk ricotta
- Fifteen ounces, whole-milk. If yours is very wet, drain it in a sieve for twenty minutes — extra water is the main reason a filling runs.
- Shredded mozzarella, divided
- One cup, split exactly in half: half a cup into the filling, half a cup over the top. Measure both before you start mixing.
- Finely grated Parmesan, divided
- Half a cup, again split — a quarter into the filling and a quarter over the top. Finely grated rather than shaved, so it melts into the filling.
- Dried sage
- A teaspoon, dried rather than fresh, in the filling. Fresh sage is listed only as an optional garnish at the end and is not a substitute for this.
How to Make It
Heat the oven and boil the shells
Heat oven to 375°F. Cook jumbo shells in salted water until just shy of al dente, then drain and cool enough to handle.
Soften the garlic
Warm the olive oil in a small skillet and cook the garlic 30 seconds, then cool slightly.
Mix the filling
Mix pumpkin, ricotta, egg, 1/2 cup mozzarella, 1/4 cup Parmesan, the garlic, dried sage, nutmeg, salt and pepper.
Sauce the dish
Spread 1 cup marinara in a 9-by-13-inch baking dish.
Fill and arrange the shells
Fill each shell with the pumpkin-ricotta mixture and arrange them in the dish.
Sauce and cheese the top
Spoon the remaining marinara around and lightly over the shells, then top with the remaining mozzarella and Parmesan.
Bake covered, then uncovered
Cover and bake 25 minutes. Uncover and bake 10 minutes more, until bubbling and the filling reaches 165°F.
Rest and garnish
Rest 5 minutes and garnish if desired.
Success Tips
- Boil a couple of spare shells — some always split, and a torn one is unfillable.
- Let the cooked garlic cool before it meets the ricotta, or it will start to warm the egg.
- A piping bag or a zip-top bag with a corner cut off fills twenty shells far faster than a teaspoon.
- Spoon the second cup of sauce around the shells rather than over them, so the tops can brown.
- Take the temperature in the middle of a centre shell, not one at the edge of the dish.
Serving Ideas
A green salad and bread for the sauce. It is rich enough that it does not want a second starch alongside it.
Storage and Reheating
Refrigerate
Refrigerate up to 4 days, covered. The shells absorb sauce overnight and the dish is arguably better the next day.
Freeze
Freezes well, either assembled and unbaked or fully baked, for up to 2 months. Thaw overnight in the fridge before baking or reheating.
Reheat
Covered, at 350°F, until hot through — around 20 minutes for a portion. Add a spoonful of marinara if the dish looks dry.
Frequently Asked Questions
Can this be made in a slow cooker?
This recipe is written for the oven at 375°F and its covered-then-uncovered timing is what browns the cheese and sets the filling. A slow cooker does neither of those, and no slow-cooker time is published here.
Why is my filling loose?
Almost always wet ricotta. Drain it in a sieve first if it is sitting in liquid in the tub. Skipping the egg does the same thing — that is the binder.
How is this different from the baked pumpkin gnocchi?
Structure. This is twenty shells individually filled with a ricotta mixture and baked in tomato marinara. The gnocchi dish has no filling and no tomato at all — packaged potato gnocchi are tossed in a pumpkin cream sauce and baked in it.
Can I fill the shells the day before?
Yes. Assemble the whole dish, cover it and refrigerate. Add roughly ten minutes to the covered bake since it starts cold, and still check for 165°F before uncovering.
