- 16oz Pasta of your choice: Use rigatoni for sturdy bites or fettuccini for a traditional feel, but any pasta that holds sauce well will do.

- 1 & 5/6 cup parmesan cheese: The essential cheesy goodness that enriches the dishes in every layer.

- 1/4 tsp nutmeg: Just a dusting to complement the creaminess without overpowering.

How to Make Chicken Alfredo Pasta Bake (With Pearl Onions)
Step 1: Perfecting the Alfredo Sauce
The foundation of our Chicken Alfredo Pasta Bake (With Pearl Onions) is a rich, creamy Alfredo sauce that clings to every strand of pasta. Starting by melting butter and whisking in flour creates a smooth roux, which thickens the sauce without any lumps. Slowly adding heavy cream, 2% milk, and Parmesan cheese builds that signature gooey, cheesy texture we all adore. Don’t forget the minced garlic and a pinch of pepper – they add a subtle but essential depth of flavor. Give it time to reduce gently; the thicker the sauce, the more luxurious your bake will be.
Step 2: Creating the Creamy Pearl Onions with Broccoli
While the sauce is simmering, it’s time to prepare the star vegetable combo that adds both texture and flavor contrasts. Boiling frozen pearl onions and tender broccoli softens them just right before coating them in a velvety sauce made from butter, flour, chicken broth, cream, parmesan, and a sprinkle of nutmeg. After mixing these ingredients on the stovetop, you transfer everything to a baking dish, crown it with extra parmesan, and bake until the top turns beautifully golden brown. The result is a luscious side that melts wonderfully into the pasta bake.
Step 3: Baking Tender, Flavor-Packed Chicken
Chicken breast cubes get a serious flavor upgrade with a marinade that’s equal parts savory and sweet. The combination of light brown sugar, aromatic Italian seasoning, smoked paprika, garlic powder, dried onions, and a touch of pepper works magic when mixed with mayonnaise and a generous splash of lemon juice. This keeps the chicken juicy and imparts a tangy richness. Baking the chicken at 375 degrees until perfectly cooked ensures that every bite is moist and bursting with savory spice.
Step 4: Assembling the Bake
Boil your pasta until tender, then combine everything like a delicious family reunion. Start by folding the Alfredo sauce into the drained pasta, then gently mix in the creamy pearl onions and the baked chicken, scraping every bit from their dishes to maximize flavor. This final step brings all elements together for a dish that’s smooth, cheesy, and packed with bursts of sweet onion and smoky chicken. Serve while hot, and get ready to savor every spoonful of this unforgettable Chicken Alfredo Pasta Bake (With Pearl Onions).
How to Serve Chicken Alfredo Pasta Bake (With Pearl Onions)
Garnishes
A sprinkle of fresh chopped parsley adds the perfect pop of color and fresh vibrancy against the creamy backdrop. For a touch of indulgence, freshly grated Parmesan on top melts slightly with residual heat, creating a cheesy crown. If you’re feeling adventurous, a light drizzle of truffle oil or a few red pepper flakes can add a gourmet twist to each serving.
Side Dishes
This dish is hearty, so simple, fresh sides work best. A crisp green salad with a tangy vinaigrette cuts through the creaminess beautifully, while roasted or steamed asparagus adds a satisfying crunch. Garlic bread or warm, crusty rolls offer the perfect vehicle for mopping up any extra Alfredo goodness left on the plate.
Creative Ways to Present
For gatherings, consider serving the pasta bake family-style in your favorite rustic casserole dish. Individual ramekins can turn this comfort meal into elegant personal servings, perfect for dinner parties. If you want to get playful, garnish each portion with a lemon wedge or edible flowers to brighten up the plate and surprise your guests.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftovers of the Chicken Alfredo Pasta Bake (With Pearl Onions) in an airtight container in the refrigerator. It will stay fresh for up to 3-4 days, making it ideal for quick lunches or reheated dinners later in the week.
Freezing
This pasta bake freezes quite well. Portion it into freezer-safe containers before baking or after cooling completely and store for up to 2 months. To prevent freezer burn, wrap the container with an extra layer of aluminum foil if possible. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
Reheat gently in the oven at 350 degrees until warmed through, about 15-20 minutes, for the best texture. Alternatively, microwave on medium power in short bursts, stirring occasionally, to prevent drying out. Adding a splash of milk can help restore creaminess during the reheating process.
FAQs
Can I use fresh pearl onions instead of frozen?
Absolutely! Fresh pearl onions can be used and simply need to be peeled and blanched before adding to the dish. They offer a slightly brighter flavor but require a bit more prep time.
Is there a substitute for heavy cream in the Alfredo sauce?
You can use half-and-half or a mixture of milk and cream cheese to achieve a creamy texture, but heavy cream really provides that rich, velvety consistency that defines a classic Alfredo sauce.
Can I make this recipe dairy-free?
While this recipe relies heavily on dairy for creaminess and flavor, you could experiment using plant-based cream alternatives and vegan cheese options, though the taste and texture will differ from the original.
What kind of pasta works best for this bake?
Sturdier pastas like rigatoni, penne, or rotini hold up well because they catch the sauce in their nooks and crannies. Traditional fettuccini works too if you prefer a silky and ribbon-like bite.
Can I add mushrooms to the dish?
Yes, mushrooms are a wonderful addition. Incorporating canned or fresh mushrooms into the pearl onion mixture before baking adds an earthy depth. Just be sure to sauté fresh mushrooms first to reduce moisture.

Melt 2 1/2 Tbsp butter in a saucepan over medium heat. Whisk in 2 1/2 Tbsp flour to form a paste. Gradually whisk in 1/2 cup heavy cream, stirring until smooth. Sprinkle in nutmeg and stir.
