I first made this Slow Cooker Spinach Pasta Primavera on a rainy weeknight when I wanted pasta without standing over the stove. The crockpot turns raw pasta and a pile of fresh vegetables into a creamy, hands-off dinner that feels a little indulgent but is mostly vegetables — perfect for busy evenings or a relaxed weekend lunch. If you like convenient slow-cooker pasta dinners, you might also enjoy this slow-cooker chicken pot pie pasta for another comfort-meets-convenience option.
Why you’ll love this dish
This recipe gives you a one-vessel, low-effort dinner that stretches a modest grocery run into a colorful, satisfying meal. It’s ideal when you want something:
- Mostly hands-off: dump, pour, and let the slow cooker do the work.
- Veg-forward: lots of fresh vegetables with quick wilted spinach added at the end.
- Family-friendly: mild, creamy, and easy to adapt for kids.
- Time-smart: ready in about 2 1/2–3 hours on LOW — great for afternoons or early evenings.
"A lone pot of pasta that tastes like it took all evening — creamy, bright with vegetables, and unbelievably easy." — a quick note from a family dinner review
How this recipe comes together
This is a straightforward slow-cooker build. First you layer chopped vegetables, aromatics, and seasoning in the pot. Next you add the uncooked short pasta on top (no stirring so the pasta cooks evenly). A warmed liquid mix of broth, cream, and grated Parmesan goes over the pasta to just barely cover it. Cook on LOW for 2 1/2 to 3 hours, stir once gently, then fold in fresh spinach and finish with extra Parmesan. The result is creamy, saucy, and studded with tender veggies.
What you’ll need
Gather these ingredients before you start. Small swaps work if you’re smart about liquid and timing.
- 8 oz uncooked short pasta (penne, rotini, or shells)
- 3 cups low-sodium vegetable broth (or chicken broth)
- 1 cup heavy cream or half-and-half (for lighter texture)
- 1 cup grated Parmesan cheese, divided (3/4 cup for sauce, 1/4 cup for serving)
- 3 cups fresh baby spinach, loosely packed
- 1 cup broccoli florets, bite-sized
- 1 cup sliced carrots (about 2 medium)
- 1 cup sliced bell peppers (any color)
- 1 cup halved cherry or grape tomatoes
- 1/2 cup frozen peas (no need to thaw)
- 3 cloves garlic, minced
- 1 small yellow onion, finely chopped
- 2 tbsp olive oil or melted butter
- 1 tsp dried Italian seasoning
- 1/2 tsp dried basil (optional)
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper
- Pinch of red pepper flakes (optional)
- Fresh parsley or extra spinach leaves, chopped (optional for garnish)
Substitution notes: use half-and-half for a lighter sauce; swap pecorino or Asiago for Parmesan if you like bolder flavor. For a dairy-free version, use full-fat coconut milk plus a dairy-free "Parmesan" or nutritional yeast (see Variations).

Step-by-step instructions
Follow these actions in order. Keep steps short and clear.
- Lightly grease the slow cooker insert with spray or a thin layer of olive oil or butter.
- Add the chopped onion, broccoli, sliced carrots, sliced peppers, frozen peas, and halved cherry tomatoes into the slow cooker. Drizzle with the olive oil. Sprinkle the minced garlic, Italian seasoning, dried basil (if using), salt, black pepper, and red pepper flakes on top. Toss very gently to coat.
- Pour the uncooked pasta over the vegetables. Do not stir — the pasta should sit on top.
- In a medium bowl, whisk together the vegetable (or chicken) broth and heavy cream until combined. Stir in 3/4 cup grated Parmesan until it mostly dissolves.
- Gently pour the broth-and-cream mixture over the pasta and vegetables. The liquid should just barely cover the pasta pieces. If some pasta sticks up, that’s okay.
- Cover and cook on LOW for 2 1/2 to 3 hours, checking at about 2 hours 15 minutes and stirring gently halfway through to ensure even cooking. Exact time depends on slow cooker model. The pasta should be tender but not mushy.
- Once the pasta is cooked, add the fresh baby spinach and fold it into the hot pasta and sauce until wilted — this takes 1–2 minutes. Taste and adjust seasoning with extra salt, pepper, or red pepper flakes.
- Sprinkle the remaining 1/4 cup Parmesan over the top, cover for 5 minutes to let flavors meld, then serve in warm bowls with parsley or extra spinach and more Parmesan at the table.
Best ways to enjoy it
This pasta is a complete meal on its own but pairs well with simple sides:
- A crisp green salad with lemon vinaigrette to cut the creaminess.
- Garlic bread or toasted baguette slices for mopping up sauce.
- Light protein like grilled shrimp or a lemony roast chicken for extra heft.
- For a wine pairing: a unoaked Chardonnay or a light-bodied Pinot Grigio complements the cream and vegetables.
If you want to serve family-style, keep the slow cooker on the warm setting and pass extra Parmesan separately.
Storage and reheating tips
Leftovers keep well if handled safely.
- Refrigeration: Cool to room temperature no more than 2 hours after cooking, then store in an airtight container for up to 3–4 days.
- Reheating (stovetop): Add a splash of broth or cream to the pasta and rewarm gently over low heat, stirring until heated through and creamy. This helps prevent separation.
- Reheating (microwave): Cover loosely and heat in 60–90 second intervals, stirring and adding a tablespoon of liquid as needed.
- Freezing: Cream-based pasta can change texture after freezing. If you must freeze, portion into airtight containers and freeze up to 2 months. Thaw overnight in the fridge and reheat slowly with extra liquid. For best texture, consider freezing without the cream and adding fresh cream when reheating.
Food safety note: Always refrigerate within two hours and reheat to steaming hot (165°F / 74°C) before serving.
Pro chef tips
Little adjustments improve texture and flavor.
- Timing matters: Cook on LOW; HIGH will overcook pasta or make the sauce separate. Check early — slow cooker temperatures vary.
- Keep pasta uncovered when stirring: use a silicone spatula and lift from the bottom so veggies don’t get smashed.
- Parmesan strategy: Stir most into the hot liquid so it helps thicken the sauce; reserve a little for finishing.
- Prevent mushy pasta: use short pasta shapes that hold up (penne, rotini, shells). If you prefer al dente, check at 2 1/2 hours.
- Brightness boost: finish with lemon zest or a squeeze of lemon juice for contrast if the dish tastes too rich.
- To stretch the meal: add cooked shredded chicken or white beans at the end for protein without changing cook time.

Creative twists
Change this dish to suit diets or moods:
- Vegetarian: follow the recipe as written, using vegetable broth.
- Dairy-free: replace cream with canned full-fat coconut milk and swap Parmesan for nutritional yeast; add a splash of lemon to brighten.
- Protein add-in: stir in cooked chicken, sausage slices, or cooked chickpeas at the end.
- Tomato-forward: use fire-roasted diced tomatoes (drained) for a tangier base — reduce broth by 1/4 cup.
- Spicy: double the red pepper flakes and top with pickled peppers for heat contrast.
- One-pot stovetop version: sauté veggies first, add pasta and liquid, simmer until pasta is al dente for a quicker version (see video tutorials for timing).
Your questions answered
Q: Can I use whole-wheat or gluten-free pasta?
A: Yes. Whole-wheat pasta will absorb liquid faster; check at 2 hours 15 minutes. Gluten-free pasta can become gummy — choose a brand that holds up and test early.
Q: Can I double the recipe to feed a crowd?
A: You can, but use a larger slow cooker and increase cooking time slightly. Keep an eye on pasta doneness and add liquid in small increments — you want pasta just covered.
Q: What size slow cooker is best?
A: A 4- to 6-quart slow cooker is ideal for this 8 oz pasta recipe. A very small cooker will crowd ingredients; a very large one may cause uneven cooking.
Q: Is it safe to leave dairy in the slow cooker for several hours?
A: Yes, when cooked on LOW and consumed promptly. The cream is mixed with hot broth which keeps it safe; avoid leaving the finished dish on warm for more than a few hours to prevent texture and safety issues.
