Stuffed Jumbo Shells with Roasted Garlic Ricotta Step-by-step instructions

Before you start

Preheat the oven to 400°F (200°C) to roast the garlic. While the garlic roasts, bring a large pot of salted water to a boil for the shells. Have all your ingredients measured and ready: ricotta, mozzarella, Pecorino, spinach, and marinara.

You will also need a baking dish, a piping bag or zip-top bag, and a hand mixer or sturdy spoon for the filling. Once the garlic is done, lower the oven to 375°F (190°C) for baking.

Instructions

Prep and Filling

1. 1Roast the Garlic and Prep the Shells
   Preheat the oven to 400°F (200°C). Cut the top off each garlic head to expose the cloves, drizzle with a little olive oil, wrap in foil, and roast until soft and golden, about 40 minutes. Let cool slightly, then squeeze the cloves out. Meanwhile, bring a large pot of salted water to a boil. Add the jumbo shells and cook according to package directions until just al dente, about 8-10 minutes. Drain and rinse with cool water.
   Look for The garlic is soft and caramelized; the shells are tender but still firm enough to hold their shape.
   Tip Do not overcook the shells – they will bake further in the oven. Rinsing with cool water stops the cooking.
2. 2Make the Ricotta Filling
   In a large bowl, combine the ricotta, roasted garlic cloves, shredded mozzarella, grated Pecorino, and chopped spinach. Use a hand mixer or a sturdy spoon to whip the mixture until smooth and creamy. Season with salt and black pepper to taste. The filling should be thick but spreadable.
   Look for The filling is uniform, creamy, and flecked with green spinach.
   Tip For a smoother filling, use a food processor. Be careful not to overmix – you want some texture.

The kitchen smells of sweet roasted garlic. The shells are cooked and cooled, lying on a baking sheet. The filling is a smooth, pale green-tinted mixture, creamy and thick.

Taste it – it should be well-seasoned and garlicky but not overpowering. The marinara is spread in the baking dish, ready to receive the stuffed shells.

Stuffing and Baking

3. 3Pipe the Filling into the Shells
   Spread the marinara sauce evenly over the bottom of a 9x13-inch baking dish. Transfer the ricotta mixture to a piping bag or a zip-top bag with the corner snipped off. Pipe the filling into each cooked shell, filling generously. Arrange the filled shells in the baking dish in a single layer, snugly together.
   Look for The shells are plump and full, nestled in a bed of red sauce.
   Tip Don't overfill – leave a little room for the shells to expand slightly during baking.
4. 4Bake the Shells
   Preheat the oven to 375°F (190°C). Sprinkle any remaining mozzarella over the tops of the shells. Cover the dish with foil and bake for 15 minutes. Uncover and bake for an additional 7-10 minutes, until the sauce is bubbling and the cheese is golden and melted. The internal temperature of the filling should reach 165°F (74°C) if using a thermometer.
   Look for The sauce bubbles around the edges and the cheese is blistered and golden.
   Tip If the top browns too quickly, cover loosely with foil for the last few minutes.

The filled shells are nestled in the sauce, each one plump and overflowing with filling. As they bake, the sauce begins to bubble, and the cheese on top melts and turns golden. The aroma of marinara and garlic fills the kitchen. The shells look glossy and inviting, with the cheese forming a bubbly, browned crust.

Finishing and Serving

5. 5Garnish and Serve
   Remove the baking dish from the oven and let it rest for 5 minutes. Tear fresh basil leaves over the top. Use a spatula to lift out the shells, making sure to get some sauce with each serving. The cheese should pull in long, stretchy strands.
   Look for The shells are golden, the cheese is stretchy, and the basil adds a fresh aroma.
   Tip Letting the dish rest helps the shells hold their shape when serving.

The dish comes out of the oven with the cheese blistered and golden, and the sauce still bubbling. Fresh basil leaves add a bright green contrast. When a shell is lifted, the mozzarella stretches in long, gooey strands. The shells are tender but hold their shape, and the filling is creamy and hot.

Common mistakes

Overcooking the shells is a common mistake – they will become too soft and tear when filling. Cook them just until al dente, and rinse with cool water to stop the cooking.

Another pitfall is under-seasoning the filling; roasted garlic is sweet, so be sure to add enough salt and pepper to balance it. Also, do not skip the foil during the initial bake, as it traps steam and helps the shells cook evenly without drying out.

How to tell it’s done

The shells are done when the sauce is bubbling around the edges and the cheese on top is melted and golden brown, with a few darker spots.

The filling should be hot throughout; if using a thermometer, it should read 165°F (74°C). Let the dish rest for 5 minutes before serving to allow the shells to set slightly and the cheese to cool enough to avoid burning mouths.
