Comfort food that’s quick, creamy, and crowd-pleasing — this One Pot Chicken and Peas Fettuccine Alfredo is the weeknight dinner you’ve been waiting for. Imagine tender cubes of chicken seared to a golden edge, fettuccine cooked right in a rich cream and chicken-broth base, and little pops of sweet green peas throughout. It’s everything you love about classic Alfredo, but with fewer dishes and far less fuss.

Why you’ll love this recipe

This version of One Pot Chicken and Peas Fettuccine Alfredo keeps things simple without skimping on flavor. Cooking the pasta and sauce together lets the fettuccine absorb flavor directly from the broth and cream, while stirring releases the pasta’s starches to thicken the sauce naturally. The result is a silky, clinging sauce that coats every strand, dotted with tender chicken and bright peas for contrast. It’s fast, satisfying, and perfectly balanced.

Ingredients

Use the following measured ingredients exactly as listed for best results:

▢2 chicken breasts (boneless and skinless, cut into cubes)
▢salt and pepper (to taste)
▢1 tablespoon olive oil
▢3 cloves garlic (minced)
▢2 cups chicken broth (low sodium)
▢1½ cups heavy cream
▢8 ounce fettuccine
▢1 cup frozen peas
▢1 sprig basil
▢1½ cups Parmesan cheese (grated)

Tools you’ll need

Large deep skillet or wide pot with a lid
Wooden spoon or heatproof spatula
Chef’s knife and cutting board
Measuring cups and spoons
Grater (if grating your own Parmesan)

Prep tips

Cut the chicken into evenly sized cubes so they cook uniformly.
Measure the chicken broth and heavy cream before you begin so everything is ready to go.
Break the fettuccine in half if your pot can’t accommodate long pasta comfortably; either method works.
Grate the Parmesan fresh for the creamiest, most flavorful sauce.

Step-by-step instructions

Follow these rewritten, clear steps to make the dish. The order matches the original recipe flow and keeps ingredient quantities unchanged.

Season the cubed chicken breasts with salt and pepper to taste. Toss or pat the seasoning onto each piece so the flavour is evenly distributed.
Heat 1 tablespoon olive oil in a large deep skillet or wide pot over medium-high heat. Once the oil shimmers, add the seasoned chicken cubes in a single layer. Sear the chicken, stirring occasionally, until the pieces are golden brown on the outside and cooked through, about 5–7 minutes depending on size. Remove the chicken from the skillet and set aside on a plate.
Reduce the heat to medium. Add the minced garlic to the same skillet and sauté for about 30 seconds to 1 minute, stirring constantly so the garlic softens but does not burn. Scrape up any browned bits from the bottom of the pan to capture flavor.
Pour in 2 cups chicken broth (low sodium) and 1½ cups heavy cream. Stir to combine, bring the liquid to a gentle simmer, and scrape the bottom of the skillet again to dissolve any remaining fond. Keep the heat at a low simmer so the cream does not boil vigorously.
Add the 8 ounce fettuccine to the simmering liquid. If the pasta is longer than the diameter of your pan, gently press it into the liquid and allow the softened ends to sink in; the pasta will soften and submerge as it cooks. Stir the pasta frequently to prevent it from sticking together or to the pan, and to encourage the release of starch that will thicken the sauce.
Return the cooked chicken to the skillet roughly halfway through the pasta’s cooking time so it warms through and finishes absorbing some of the sauce flavors. Continue stirring occasionally to ensure even cooking and to keep the pasta separate.
When the fettuccine is about one minute away from al dente (tender but with a slight bite), stir in 1 cup frozen peas. The residual heat and simmer will thaw them quickly and keep them bright green and tender-crisp.
Turn off the heat. Add 1½ cups grated Parmesan cheese to the skillet and stir vigorously until the cheese melts and the sauce becomes glossy and creamy. Taste, then adjust seasoning with additional salt and pepper if needed. The cheese will thicken the sauce as it melts, giving it that classic Alfredo texture.
Pick 1 sprig basil and chop or tear the leaves; stir most of the basil into the pasta, reserving a few leaves for garnish. This adds a fresh, herbal note that brightens the rich sauce.
Serve immediately, spooning generous portions of the pasta, chicken, and peas into bowls or onto plates. Top each serving with the reserved basil and an extra sprinkle of grated Parmesan if desired.

Serving suggestions

This One Pot Chicken and Peas Fettuccine Alfredo shines on its own, but you can elevate the meal with a few simple additions:

Green side salad with a light lemon vinaigrette to cut through the richness.
Crusty bread or garlic bread for sopping up leftover sauce.
Sautéed mushrooms or roasted cherry tomatoes folded in for extra color and flavor.
A squeeze of fresh lemon over each plate for a bright finish.

Make-ahead and storage

If you need to prep ahead, cook the chicken and stash it separately in the fridge for up to 2 days. When ready to eat, reheat the chicken gently and add it back while finishing the pasta. Leftovers should be kept in an airtight container and refrigerated for up to 3 days. To reheat, warm gently on the stovetop with a splash of chicken broth or cream to loosen the sauce; avoid high heat to prevent the sauce from separating.

Notes and variations

If you prefer a lighter sauce, substitute half-and-half for some of the heavy cream, but be aware the sauce will be slightly less thick and indulgent.
For a dairy-free twist, use a creamy, unsweetened plant-based cream and a vegan Parmesan alternative—adjust seasoning to taste as those substitutes behave differently.
Swap the peas for fresh asparagus tips or spinach for seasonal variation. If using fresh spinach, stir it in at the end until wilted.
For more herb flavor, add chopped parsley along with the basil or finish with a pinch of cracked red pepper for heat.

Why this method works

Cooking the pasta directly in the sauce liquids concentrates flavor and allows the pasta starch to naturally thicken the sauce, producing that silky coating we all crave in an Alfredo. Searing the chicken first locks in juices and develops browned flavor, while finishing everything together lets the components meld without overcooking the pasta or the chicken. The quick addition of frozen peas keeps them bright and texturally pleasing.

Final thoughts

Easy, creamy, and ready in under 30 minutes, this One Pot Chicken and Peas Fettuccine Alfredo is a go-to for busy nights when you want something impressive without the fuss. The single-pot approach means less cleanup and more time at the table enjoying the dish.

Happy cooking — and enjoy every silky, cheesy forkful!
