Ingredients

Servings: 4

8 oz dry angel hair pasta (about half of a 16 oz box)
3 cups low-sodium chicken broth
1 (24 oz) jar tomato basil pasta sauce
1 cup heavy cream (or half-and-half for lighter)
1 cup grated Parmesan cheese, plus extra for serving

Ingredient Notes

Dry angel hair pasta: Use dry angel hair pasta. Do not use fresh pasta. Do not use whole wheat pasta. Angel hair is thin and delicate and cooks perfectly in the slow cooker. Break the pasta in half before adding to the slow cooker so it fits and cooks evenly.

Low-sodium chicken broth: Low-sodium broth is essential. The pasta sauce and Parmesan cheese both contain salt. Low-sodium broth prevents the dish from becoming too salty. Vegetable broth can be substituted.

Tomato basil pasta sauce: Use a 24-ounce jar of tomato basil pasta sauce. The basil adds herbaceous notes that complement the cream and Parmesan. Marinara or tomato garlic sauce also work. Do not use a sauce with large vegetable chunks.

Heavy cream: Heavy cream creates a rich, luxurious, velvety sauce. Half-and-half can be substituted for a lighter result. Do not use milk, which may curdle.

Grated Parmesan cheese: Use finely grated Parmesan cheese. Pre-shredded Parmesan contains anti-caking agents that may affect melting. Grate your own from a block for the best results.

Step-by-Step Instructions

Step 1: Prepare the Slow Cooker

Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick cooking spray or a thin film of olive oil. This helps prevent the pasta from sticking.

Step 2: Add the Pasta

Break the dry angel hair pasta in half. Scatter it evenly over the bottom of the slow cooker. This is your base layer and should resemble a loose nest of raw strands.

Step 3: Make the Sauce

In a large bowl or measuring pitcher, whisk together the chicken broth and tomato basil pasta sauce until well combined. Stir in the heavy cream.

Step 4: Add the Sauce

Pour the tomato-broth-cream mixture evenly over the dry angel hair. Press the pasta down gently with a spoon or tongs so most of it is submerged. Some strands may peek out. They will soften as they cook.

Step 5: Add the Parmesan

Sprinkle the grated Parmesan cheese evenly over the top. Do not stir yet. Letting the cheese sit on top helps it melt into the sauce gradually.

Step 6: Slow Cook

Cover the slow cooker with the lid. Cook on LOW for 1 hour.

Step 7: Toss Halfway Through

After 30 to 40 minutes, quickly lift the lid. Gently toss the pasta with tongs to separate the strands and coat them in the sauce. Cover again promptly to retain heat.

Step 8: Check for Doneness

After 1 hour total, check the pasta. Angel hair cooks quickly. It should be just tender (al dente) and coated in a creamy, slightly thickened sauce. If it is still too firm or the sauce seems thin, cover and cook an additional 10 to 15 minutes on LOW, tossing once more.

Step 9: Finish and Serve

Once the pasta is cooked to your liking, give everything a final gentle toss. Ensure the angel hair is fully coated and not clumped. Taste and adjust seasoning with a pinch of salt or extra Parmesan if desired. Serve immediately while hot, with extra Parmesan on the table.

How to Serve Slow Cooker Angel Hair

This creamy tomato pasta is delicious on its own, but a few simple additions can elevate it.

With Extra Parmesan: A generous sprinkle of freshly grated Parmesan on top.

With Fresh Basil: Chopped fresh basil adds brightness and color.

With Red Pepper Flakes: A pinch of red pepper flakes adds heat.

With Grilled Chicken: Top with sliced grilled chicken for extra protein.

With Shrimp: Add cooked shrimp during the last 5 minutes of cooking.

With Sautéed Mushrooms: Sautéed mushrooms add earthy depth.

With a Green Salad: A simple salad with a tangy vinaigrette cuts through the richness.

With Garlic Bread: Crusty garlic bread is perfect for sopping up extra sauce.

Variations & Tips

Make It With Vodka Sauce: Use vodka sauce instead of tomato basil sauce. The result is a creamy vodka pasta.

Make It With Spinach: Add 2 cups of fresh spinach during the last 10 minutes of cooking. Stir until wilted.

Make It With Chicken: Add 1 cup of cooked, shredded chicken along with the sauce.

Make It With Sausage: Add 1/2 cup of cooked Italian sausage crumbles.

Make It With Mushrooms: Add 1 cup of sliced sautéed mushrooms.

Make It With Half-and-Half: Substitute half-and-half for the heavy cream for a lighter sauce.

Make It Dairy-Free: Use full-fat coconut milk instead of heavy cream. Use dairy-free Parmesan.

Make It Gluten-Free: Use gluten-free angel hair pasta. Add 1/4 cup more broth, as gluten-free pasta absorbs more liquid.

Make It in a Large Skillet: Combine ingredients in a large skillet. Simmer over medium heat for 10 to 15 minutes, stirring frequently, until pasta is tender.

Pro Tips for Absolute Success

Break the pasta in half. Angel hair is long. Breaking it in half helps it fit in the slow cooker and makes it easier to toss.

Do not stir at the beginning. Let the pasta settle naturally. Stirring too early can cause clumping.

Toss halfway through. A gentle toss at 30 to 40 minutes separates the strands and ensures even cooking.

Do not overcook. Angel hair cooks quickly. Check at 1 hour. If it is done, turn off the slow cooker immediately.

Serve immediately. Angel hair continues to soften as it sits. For the best texture, serve as soon as it is cooked.

Use low-sodium broth. The Parmesan and pasta sauce provide plenty of salt. Low-sodium broth prevents the dish from becoming too salty.

Frequently Asked Questions

Can I use a different pasta?
Angel hair is recommended because it cooks quickly. Spaghetti or linguine can be used but may require a longer cook time. Do not use thick pasta like penne or rotini.

Can I use water instead of broth?
Yes. Water will work, but the dish will be less flavorful. Use broth if you have it.

Can I use milk instead of heavy cream?
Milk is not recommended. It may curdle in the slow cooker. Half-and-half is the best lighter option.

Can I add meat to this dish?
Yes. Add cooked chicken, shrimp, or Italian sausage during the last 10 minutes of cooking.

My pasta is clumped together. What went wrong?
You did not toss it halfway through, or you used too much pasta. Toss gently at 30 to 40 minutes. Use 8 ounces of pasta, not more.

My sauce is too thin. What do I do?
Cook uncovered for an additional 10 to 15 minutes to allow excess liquid to evaporate. The sauce will thicken as it cools slightly.

My sauce is too thick. What do I do?
Stir in warm broth or milk, one tablespoon at a time, until it reaches your desired consistency.

Can I double this recipe?
Only if your slow cooker is at least 6 quarts. Do not fill more than two-thirds full. If doubling, add 15 to 20 minutes to the cook time.

Can I freeze the leftovers?
Freezing is not recommended. The texture of the pasta and cream sauce will degrade upon thawing. The sauce may separate.

How long do leftovers last in the refrigerator?
Store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of broth or milk.

The Slow Cooker Pasta Secret

Most people do not think of the slow cooker for pasta. They think of the stovetop. A pot of boiling water. A colander. A separate pan for the sauce. The slow cooker changes all of that.

When you cook pasta directly in the sauce, something wonderful happens. The pasta releases starch as it cooks. That starch thickens the liquid into a silky, clingy sauce. The pasta absorbs the flavors of the broth, tomato, and cream. Everything becomes one cohesive dish.

This angel hair is a perfect example. In just one hour, raw pasta transforms into a creamy, luxurious meal. No boiling. No draining. No separate sauce pan. Just a slow cooker, a few ingredients, and a little patience.

Keep angel hair in your pantry. Keep broth and pasta sauce in your cupboard. Keep cream and Parmesan in your fridge. This recipe is the reason why.
