Ingredients You’ll Need

With just a handful of pantry staples and a few clever additions, French Onion Chicken Bubble Up is as simple as it is delectable. Each ingredient is carefully chosen to add something special—whether it’s creamy texture, cheesy stretch, or those comforting, unmistakable flavors of a timeless casserole.

Cooked chicken, shredded (2 cups): Use rotisserie, leftover, or freshly cooked chicken for juicy and flavorful bites throughout the casserole.
Refrigerated biscuit dough, cut into quarters (1 can, 8 oz): These little dough nuggets bubble up into buttery, pillowy pockets that soak up all the flavor.
French onion soup (1 can, 10.5 oz): This is the magic ingredient, infusing every bite with sweet, savory depth and a hint of caramelized onion goodness.
Sour cream (1 cup): Adds ultra-creaminess and a gentle tang that perfectly balances the richness of the dish.
Shredded mozzarella cheese (1 cup): Ensures every spoonful is packed with gooey, stringy cheese pulls.
Grated Parmesan cheese (1/2 cup): Melts beautifully on top, giving a nutty, golden finish.
Butter, melted (2 tablespoons): Helps crisp up the top while infusing even more buttery flavor.
Garlic powder (1/2 teaspoon): A little goes a long way for a fragrant, savory boost.
Onion powder (1/2 teaspoon): Amplifies the onion flavor, making the French onion notes unmistakable.
Salt and pepper to taste: These finishing touches let you season the casserole exactly how you love it.

How to Make French Onion Chicken Bubble Up

Step 1: Prep Your Baking Dish and Ingredients

Start by preheating your oven to 375°F (190°C) so it’s ready for bubbly action. Lightly grease a 9×13-inch baking dish—this little step ensures your biscuits brown up beautifully and serving is a breeze. While the oven heats, quarter the biscuit dough and shred or chop your cooked chicken for a quick assembly.

Step 2: Mix Everything Together

Grab a large bowl—this is where the magic begins. Add the shredded chicken, quartered biscuit pieces, French onion soup, sour cream, mozzarella cheese, Parmesan cheese, garlic powder, and onion powder. Gently stir everything together until the biscuits are coated and every ingredient is evenly distributed. It’ll look rich, creamy, and absolutely packed with flavor already!

Step 3: Assemble the Casserole

Pour the chicken-biscuit-cheese mixture into your prepared baking dish. Spread it out evenly so every nook and cranny gets filled with flavor. This is your canvas, so try to distribute everything as uniformly as possible for the perfect bubble up in every bite.

Step 4: Add the Finishing Touches

Drizzle the luscious melted butter over the top. Don’t skip this step—the butter crisps and browns the top beautifully while infusing the final bake with delicious richness. Give it a quick sprinkle of salt and pepper for that burst of seasoning on the crispy edges.

Step 5: Bake to Golden, Bubbling Perfection

Slide your casserole into the oven and bake for 35–40 minutes. You’re looking for biscuits that are fully cooked, puffed and golden, and a top that’s deliciously bubbly and speckled with melty cheese. Allow it to cool just a few minutes before you dig in; this makes serving easier and keeps the biscuit pieces intact.

How to Serve French Onion Chicken Bubble Up

Garnishes

A sprinkle of fresh parsley, chopped chives, or just a little extra Parmesan right before serving does wonders for French Onion Chicken Bubble Up. Not only do these add a pop of color, but that extra burst of freshness and flavor makes each serving even more inviting.

Side Dishes

This casserole truly shines with simple, fresh accompaniments. Think a crisp green salad, lightly steamed green beans, or roasted carrots. A side of garlicky sautéed spinach or crusty French bread is also a lovely way to complete your meal without overshadowing the star of the show.

Creative Ways to Present

For an extra-special touch, try dividing the mixture into individual ramekins or mini baking dishes for single servings of French Onion Chicken Bubble Up. Or, garnish each plate with an extra slice of melted cheese and a swirl of French onion soup for a restaurant-worthy presentation at home.

Make Ahead and Storage

Storing Leftovers

Keep leftover French Onion Chicken Bubble Up in an airtight container in the refrigerator for up to three days. The flavors continue to meld and deepen, making leftovers just as comforting as the first bite.

Freezing

This casserole freezes well! Let the baked dish cool completely, then wrap tightly with foil or plastic wrap and freeze for up to two months. Thaw overnight in the fridge before reheating for the best texture and freshness.

Reheating

To reheat, cover the casserole dish with foil and warm in a 350°F oven until heated through—about 20 minutes for a whole casserole or 5–7 minutes for individual servings. A quick zap in the microwave works too, but the oven keeps those biscuit tops nice and crisp.

FAQs

Can I use rotisserie chicken in French Onion Chicken Bubble Up?

Absolutely! Rotisserie chicken is a fantastic shortcut and adds extra flavor, making meal prep even quicker and tastier.

What kind of biscuit dough works best?

Any standard canned refrigerated biscuit dough will work well. Choose your favorite brand, and feel free to use “flaky layers” for an extra-tender texture. Just be sure to cut each biscuit into quarters so they bake evenly.

Can I make French Onion Chicken Bubble Up ahead of time?

Yes! You can assemble everything a few hours ahead, cover tightly, and refrigerate until ready to bake. Just add a few extra minutes to the baking time if you’re starting from cold.

Is there a way to make this dish lighter?

For a lighter version, use reduced-fat sour cream and cheese, and substitute part-skim mozzarella. You can also increase the vegetable content by folding in a handful of spinach or steamed broccoli before baking.

What can I use if I don’t have French onion soup?

If French onion soup isn’t available, a mixture of beef broth, sautéed sweet onions, a dash of Worcestershire sauce, and a pinch of thyme can mimic those delicious flavors in a pinch.
