🍴 Why You’ll Love This Recipe

This French Onion Chicken Bubble Up is:

• Ready in under an hour
• Made with simple, affordable ingredients
• Perfect for meal prep or feeding a crowd
• Loaded with flavor from caramelized onions, Swiss cheese, and garlic
• Baked with refrigerated biscuit dough that “bubbles” up around the chicken as it bakes

Yes, you read that right — canned biscuits are the secret ingredient here. And no, it doesn’t taste like canned anything. It tastes like comfort, care, and creamy, cheesy deliciousness.

🥘 Ingredients (Serves 6–8)

For the Filling:

• 4 boneless, skinless chicken breasts (or pre-cooked shredded chicken for faster prep)
• 1 stick (½ cup) butter
• 2 large yellow onions, thinly sliced
• 1 tbsp olive oil
• 1 tsp sugar (to help onions caramelize)
• 1 tsp garlic powder
• 1 tsp dried thyme
• Salt and pepper to taste
• 1½ cups shredded Gruyère or Swiss cheese
• ¼ cup grated Parmesan cheese
• 10–12 refrigerated biscuit dough rounds (not canned biscuits — just the soft dough ones from the fridge section)
• Fresh thyme or parsley for garnish (optional)

🍳 Step-by-Step Instructions

Step 1: Preheat Your Oven

Preheat oven to 375°F (190°C) . Grease a 9×13-inch baking dish generously with butter or nonstick spray.

Step 2: Caramelize the Onions

In a skillet over medium heat:

• Melt butter and olive oil together
• Add sliced onions and sprinkle with sugar
• Cook slowly for 20–25 minutes , stirring occasionally, until deep golden brown and fragrant

Add garlic powder and thyme during the last few minutes of cooking.

Step 3: Prep the Chicken

Place chicken breasts in the bottom of the baking dish. Season lightly with salt and pepper.

Then spoon the caramelized onions and garlic mixture evenly over the top of each breast.

Step 4: Add the Cheese Layer

Sprinkle Gruyère or Swiss cheese over the onions — followed by a dusting of Parmesan for extra richness.

Step 5: Arrange the Biscuit Dough

Carefully place the refrigerated biscuit dough pieces around the chicken, gently pressing them into the cheese layer.

Don’t flatten them — they’ll puff up and spread while baking.

Step 6: Bake Until Golden and Bubbly

Bake uncovered for 25–30 minutes , or until the chicken is fully cooked, the onions are deeply golden, and the biscuit tops have risen and turned golden brown.

Let cool slightly before serving — and watch everyone reach for seconds.

🧀 Serving Suggestions

Serve this bubbly masterpiece with:

• A crisp green salad
• Roasted vegetables
• Garlic mashed potatoes
• Or even on its own — because sometimes less is more

Leftovers store well in the fridge and reheat beautifully in the oven or toaster oven to keep the crust crisp.

📦 Why Canned Biscuits Are Secretly Genius

The key to this dish is using refrigerated biscuit dough — not dry biscuit mix or pre-baked versions.

As the casserole bakes, the dough rises around the chicken, forming a golden, flaky crust that seals in moisture and flavor.

It’s like having a savory pie without the hassle — and it’s one of those recipes that looks fancy, but takes zero effort.
