There are evenings when the clock is ticking louder than my stomach, the fridge looks like a wilderness, and my family still expects something magical on the table. Years ago, on one of those very nights, I cobbled together a half-box of penne, the last chicken breast, and a forgotten head of broccoli. One creamy sauce later, this Easy Chicken and Broccoli Alfredo with Penne Pasta was born. We’ve served it at birthday sleepovers, brought it in disposable pans to new-parent neighbors, and packed it into thermoses for Friday night football. It tastes like you babysat a roux for an hour, but the truth is closer to 25 minutes and one skillet. If you need a reliable, comfort-food hero that feels restaurant-level yet uses everyday staples, bookmark this page—because weeknights are chaotic, and everyone deserves a silky forkful of pasta at the end of them.

Why This Recipe Works

One-Pot Wonder: The pasta cooks in the same skillet as the sauce, soaking up flavor and saving dishes.
30-Minute Timeline: From fridge to table faster than delivery—perfect for busy weeknights.
No Heavy Cream Needed: Whole milk, broth, and a touch of cream cheese create luscious texture without the weight.
Broccoli That Stays Green: Quick blanch in the pasta water keeps florets vibrant and tender-crisp.
Family-Approved Protein: Bite-size chicken pieces mean every forkful is balanced—no negotiating bites.
Leftover Magic: Reheats like a dream; add a splash of milk and it’s silky again.

Ingredients You'll Need

Great alfredo starts with everyday items—but a few smart choices elevate the dish from cafeteria to trattoria.

Penne Pasta: Choose a bronze-cut brand if possible. The microscopic ridges grab sauce better than Teflon-smooth varieties. Whole-wheat penne works, though you may need an extra splash of liquid at the end.

Chicken Breast: Look for plump, rosy fillets with no gray spots. Partially freeze for 10 minutes to make slicing into uniform cubes easier, ensuring even cooking.

Broccoli Florets: Buy a small head and cut it yourself; pre-cut bags are convenient but often contain more stem than flower. You want bite-size trees that will nestle inside the penne tubes.

Garlic: Fresh cloves, never the jarred stuff. Smash with the flat of a knife, let sit 1 minute—this activates allicin for maximum aroma.

Unsalted Butter & Extra-Virgin Olive Oil: A 50-50 combo prevents burning while still giving buttery flavor. Oil also raises the smoke point so your chicken sears, not steams.

All-Purpose Flour: Just two tablespoons thicken the sauce without that pasty taste. For gluten-free, substitute superfine rice flour 1:1.

Whole Milk: 2% is acceptable; anything leaner and the sauce may break. Bring to room temp before adding to the skillet to prevent curdling.

Low-Sodium Chicken Broth: Using broth instead of all milk lightens the dish and layers flavor. Low-sodium keeps you in control of seasoning.

Cream Cheese: A modest two-ounce nub adds body and that signature tang you thought only heavy cream could deliver. Neufchâtel works too.

Freshly Grated Parmesan: Pre-grated tubs contain anti-caking agents that turn sauces gritty. Buy a wedge and use the fine side of a box grater; it dissolves instantly.

Seasonings: Kosher salt, cracked black pepper, and a whisper of nutmeg amplify creaminess and make the cheese sing.

How to Make Easy Chicken and Broccoli Alfredo with Penne Pasta

Prep & Season the Chicken

Pat 1 pound of chicken breast dry, cube into ¾-inch pieces, and toss with ½ teaspoon kosher salt, ¼ teaspoon pepper, and ½ teaspoon Italian seasoning. Let rest while you heat the pan—this quick brine locks in juices.

Start the Pasta Water

Fill a medium saucepan with 4 quarts of water, cover, and bring to a boil over high heat. Salt until it tastes like the sea—about 1 tablespoon per quart. This is your only chance to season the pasta itself.

Sear the Chicken

Heat 1 tablespoon olive oil and 1 tablespoon butter in a 12-inch high-sided skillet over medium-high. When the foam subsides, add chicken in a single layer. Cook 3 minutes without stirring for a golden crust, flip, cook 2 minutes more. Transfer to a plate; the centers will finish later in the sauce.

Blanch the Broccoli

Drop 3 cups of broccoli florets into the boiling water for 90 seconds. Scoop out with a spider or slotted spoon into a bowl of ice water to set the color. Keep the water boiling—you’ll reuse it for the pasta, saving dishes and picking up a hint of broccoli sweetness.

Cook the Penne

Add 12 oz penne to the same water and cook 2 minutes less than package directions for al dente. Reserve 1 cup starchy pasta water, then drain. The pasta will finish cooking in the sauce, absorbing flavor instead of just water.

Build the Roux

Lower heat to medium, add remaining 1 tablespoon butter to the now-empty skillet. When melted, whisk in 2 tablespoons flour and cook 60 seconds to remove raw taste. You’re looking for a pale blonde paste—any darker and it will tint your alfredo.

Create the Sauce Base

Slowly pour in 1 cup room-temperature whole milk and ½ cup low-sodium chicken broth while whisking constantly. Add 2 oz cream cheese cut into cubes. Simmer 3 minutes until thick enough to coat the back of a spoon. Reduce heat to low.

Cheese & Season

Off the heat, whisk in 1 cup freshly grated Parmesan, ¼ teaspoon nutmeg, and additional salt and pepper to taste. Return skillet to low, add the drained penne, broccoli, and seared chicken. Toss everything together, adding reserved pasta water a splash at a time until the sauce is silky and clings to the tubes.

Final Simmer & Serve

Cover and let everything mingle 2 minutes more so the pasta absorbs some sauce and the chicken finishes cooking. Taste and adjust seasoning. Serve hot with extra Parmesan and a crack of black pepper.

Expert Tips

Temperature Matters

Cold dairy can split. Let milk and cream cheese sit on the counter while you chop; the sauce will stay smooth and luxurious.

Starchy Gold

Reserved pasta water contains starch that binds sauce and pasta. Add gradually—too much thins, too little leaves things clumpy.

Al Dente Insurance

Undercook pasta by 2 minutes; it will finish in the sauce and absorb the flavors rather than turning mushy.

Grate Your Own

Pre-shredded cheeses contain cellulose that can give sauces a gritty texture. A microplane turns a wedge into fluffy snow in seconds.

Make-Ahead Magic

Assemble through Step 7, refrigerate up to 24 hrs. When ready, warm gently with a splash of broth while pasta cooks.

Color Pop

Add a handful of halved cherry tomatoes with the broccoli for a burst of sweetness and a restaurant-worthy color contrast.

Variations to Try

Shrimp & Broccoli Alfredo: Swap chicken for 1 lb peeled shrimp; sear just 1 minute per side and remove, then return at the end to prevent rubbery bites.
Bacon Ranch Version: Stir in 1 tablespoon dry ranch seasoning with the flour and sprinkle crispy bacon over each serving.
Veggie Boost: Fold in roasted zucchini, bell pepper, or peas during Step 8 for extra nutrients and color.
Spicy Kick: Add ½ teaspoon crushed red pepper flakes with the garlic for a gentle heat that cuts the richness.
Gluten-Free: Use gluten-free penne and substitute rice flour in the roux—no other changes needed.
Lemon Herb Finish: Brighten the final dish with 1 teaspoon fresh lemon zest and chopped parsley for a springtime vibe.

Storage Tips

Refrigerate: Cool completely, transfer to an airtight container, and refrigerate up to 4 days. Reheat gently on the stove over medium-low with a splash of milk or broth, stirring often.

Freeze: Portion into freezer-safe zip bags, press out excess air, and freeze up to 3 months. Thaw overnight in the fridge before reheating. Note: broccoli softens slightly but flavor remains excellent.

Make-Ahead Components: Chop broccoli and cube chicken up to 2 days ahead; store separately. Grate Parmesan and keep covered in the fridge. When dinner hits, everything cooks in a flash.

Frequently Asked Questions

Absolutely. Add shredded rotisserie chicken in Step 8 so it warms through without drying out. Reduce salt slightly since the bird is preseasoned.

High heat or pre-grated cheese are common culprits. Keep the skillet over low when adding Parmesan and whisk constantly. If it’s already grainy, blitz with an immersion blender for 5 seconds to re-emulsify.

Yes, but use a wider pot or Dutch oven to maintain surface area for sauce reduction. You may need an extra splash of liquid at the end.

Substitute unsweetened oat milk and dairy-free cream cheese. Use nutritional yeast or vegan parm for the cheesy note; flavor will differ but still creamy.

A lightly oaked Chardonnay mirrors the creamy sauce, while a crisp Pinot Grigio cuts the richness. For red lovers, try a fruity Pinot Noir served slightly chilled.

Sure—use sauté mode for Steps 3 and 6, then cook pasta on high pressure for half the package time, quick release, and proceed with Step 8 on sauté-low. Add chicken and broccoli after pressure cooking to avoid overcooking.
