Spring Evening Comfort: Just 5 ingredients. I make it when I want dinner handled hours ahead and zero pots to scrub at the end of the night.

This 5-ingredient slow cooker spring shells recipe is what I lean on when I want dinner handled hours ahead and the kitchen to stay clean. Dry pasta shells cook right in the slow cooker with broth, peas, and a touch of cream and cheese, creating a velvety sauce that clings to every ridge. It’s a very Midwestern kind of comfort—pantry-friendly, practical, and cozy—yet still feels a bit like a lighter, springtime take on classic mac and cheese. No boiling water, no separate pots, and the slow cooker insert is the only thing to wash at the end of the night.

Serve these spring shells straight from the slow cooker with a simple green salad dressed in lemon and olive oil to keep the meal bright. A side of roasted asparagus or sautéed green beans echoes the peas and adds a little texture contrast. If you’d like some protein, pair with rotisserie chicken, grilled sausages, or broiled salmon. A crisp white wine like Sauvignon Blanc or a light, citrusy beer works well with the creamy, cheesy sauce, while sparkling water with a lemon wedge keeps it refreshing and weeknight-friendly.

Servings: 4

12 oz dry medium pasta shells

Lightly coat the inside of your slow cooker insert with a thin film of neutral oil or nonstick spray to help prevent sticking and make cleanup easier.

Add the dry pasta shells to the slow cooker and spread them into an even layer so they cook as uniformly as possible.

Pour the broth over the pasta, pressing down gently with a spoon to make sure most of the shells are submerged. It’s fine if a few edges peek above the liquid; they’ll soften as the mixture heats and steams.

Cover and cook on HIGH for 1 1/2 to 2 hours, stirring once around the 1-hour mark if you are home. The pasta should be just tender but not mushy, and there will still be some starchy liquid in the cooker—that’s what will turn into the sauce.

Once the shells are al dente, add the frozen peas directly to the slow cooker and stir them in. The temperature of the pasta and liquid will start to thaw them almost immediately.

Pour in the heavy cream and stir until the mixture looks loose and silky. The sauce will thicken as the cheese melts and the pasta continues to absorb some liquid.

Add the shredded Parmesan or Asiago in 2 to 3 handfuls, stirring well after each addition until fully melted and smooth. This gradual addition helps the cheese melt evenly into a glossy, velvety sauce instead of clumping.

Cover again and cook on LOW for 10 to 15 minutes, just until the peas are bright green and tender and the sauce is thick, creamy, and bubbling gently around the edges. Avoid overcooking at this stage so the peas stay vibrant and the pasta doesn’t turn soft.

Taste and adjust the seasoning with a pinch of salt and freshly ground black pepper if you like (salt is optional and not counted as one of the core ingredients). The cheese and broth may already provide enough saltiness.

Serve the spring shells straight from the slow cooker while hot, with an extra sprinkle of cheese on top if desired. Switch the slow cooker to WARM to hold for up to 30–45 minutes, giving a quick stir before serving so the sauce stays evenly glossy.

For extra spring character, you can stir in a handful of thinly sliced scallions or fresh herbs like parsley, chives, or tarragon right at the end, though this will take you beyond the strict 5-ingredient base. If you’d like more protein, fold in shredded rotisserie chicken or flaked canned tuna after the cheese melts, letting it warm through on LOW for a few minutes. To make it richer, swap half of the broth for whole milk (add the milk when you add the cream, not at the beginning, to prevent curdling). For a lighter version, use half-and-half instead of heavy cream and reduce the cheese slightly; the sauce will be a bit looser but still comforting. You can substitute small shapes like elbows or cavatappi, but avoid very large shells, which tend to cook unevenly in a slow cooker. Food safety notes: Keep frozen peas frozen until you add them; do not leave them out at room temperature for extended periods. If you add any cooked meats, be sure they are already fully cooked and reheat them in the slow cooker until they reach at least 165°F in the center. Do not leave the finished dish on the WARM setting for more than about 2 hours total; cool leftovers promptly and refrigerate within 2 hours of cooking. Reheat leftovers gently with a splash of broth or cream to loosen the sauce, stirring often to avoid scorching.
