Preheat the oven to 400°F (200°C).Lightly butter a 5×7-inch baking dish and set it aside.
Make the Biscuits
In a large bowl, whisk together the flour, baking powder, sugar, and salt.
Add cold butter and use your fingers or a pastry blender to mix until the texture resembles coarse sand.
Pour in milk and stir just until the dough comes together. Set aside.
Make the Casserole
Heat a 10-inch skillet over medium heat. Add butter and melt, then add onions and cook, stirring frequently, until translucent, about 2 minutes.
Increase heat to medium-high and add mushrooms, garlic, salt, and pepper. Cook, stirring occasionally, for 3 minutes. If the mushrooms start to stick to the pan, add a little more butter.
Pour in the chicken broth and bring to a simmer.
Stir in heavy cream and Italian seasoning, and bring to a simmer. Cook, stirring frequently, for 2 minutes.
Add sour cream and stir until smooth. Continue cooking for 2 to 3 additional minutes until the sauce thickens.
Stir in the chicken and frozen vegetables. Taste and add more salt if needed.
Spoon the chicken mixture into the prepared baking dish.
Assemble and Bake
Drop the biscuit dough by rounded spoonfuls over the casserole, spacing evenly. Some filling may peek through.
Bake for 15-17 minutes, until the biscuits are golden brown and cooked through. Let cool for a few minutes before serving. Enjoy hot!
Notes
Use the Right Baking Dish – A 5×7-inch, 6×6-inch, or 7-inch round baking dish works best for even cooking and the right biscuit-to-filling ratio.
Don’t Overmix the Biscuit Dough – Stir just until combined to keep the biscuits light and tender. Overmixing can make them dense.
Taste and Adjust Seasoning – Before adding the biscuits, taste the filling and adjust the salt or pepper if needed.
Bake on a Rimmed Baking Sheet – This helps catch any spills and keeps your oven clean.
Let It Rest Before Serving – The sauce will thicken as it cools, making it easier to serve. Let the casserole sit for about 5 minutes before digging in.
