1 cup beef or chicken broth
1 tbsp Worcestershire sauce
1 tsp Dijon mustard
For the Bubble Up Topping:
1 (16 oz) can refrigerated flaky biscuits, quartered
1 ½ cups shredded Gruyère or Swiss cheese
½ cup shredded mozzarella (for extra meltiness!)
2 tbsp chopped parsley (for garnish)
(Optional: crispy fried onions for extra crunch!)
Step-by-Step Instructions
1. Caramelize the Onions
In a large oven-safe skillet, melt butter over medium heat.
Add onions and cook 15-20 mins, stirring occasionally, until golden and sweet.
2. Cook the Chicken
Push onions to one side, add chicken, garlic powder, thyme, salt & pepper.
Cook until chicken is browned (~5 mins).
3. Make the Gravy
Stir in French onion soup, broth, Worcestershire, and Dijon. Simmer 5 mins.
4. Add the Biscuits & Cheese
Remove from heat. Arrange biscuit pieces over the mixture.
Sprinkle with Gruyère and mozzarella.
5. Bake to Perfection
Bake at 375°F (190°C) for 20-25 mins, until biscuits are golden and cheese is bubbly.
Garnish with parsley and fried onions (if using).
