Step-by-Step Cooking Instructions

    Step 1: Preheat & Prep

    • Preheat your oven to 400°F (200°C).
    • Grease a 9x13-inch baking dish and set it aside.

    Step 2: Make the Filling

    • In a large skillet, melt butter over medium heat. Add onion and garlic, cooking for 2-3 minutes until soft and fragrant.
    • Stir in the flour, cooking for 1 minute to remove the raw taste. This helps thicken the sauce.
    • Slowly whisk in chicken broth and milk, stirring constantly until the mixture thickens (about 3-5 minutes).
    • Add salt, pepper, and thyme. Stir in the chicken and vegetables, then let it simmer for 2 minutes.
    • Pour the filling into the prepared baking dish and spread evenly.

    Step 3: Make the Biscuit Topping

    • In a bowl, whisk together flour, baking powder, salt, and garlic powder.
    • Cut in cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
    • Stir in milk until a soft dough forms (don’t overmix).

    Step 4: Assemble & Bake

    • Drop spoonfuls of the biscuit dough evenly over the filling. No need to make it perfect—rustic is best!
    • Bake for 25-30 minutes, or until the biscuits are golden brown and the filling is bubbly.

    Step 5: Cool & Serve

    • Let the casserole sit for 5 minutes before serving (it’s hot!).
    • Spoon it onto plates and enjoy the creamy, cozy goodness.
    • Get ready for seconds—this one disappears fast! 😋
