Step-by-Step Instructions (Creamy, Flaky, Foolproof)
1. Make the Filling
- Preheat oven to 375°F (190°C).
- In a large skillet or Dutch oven, melt butter over medium heat.
- Add onion, celery; cook 5 minutes until soft. Add garlic; cook 1 minute.

- Arrange biscuits on top (cut in half for even coverage).
- Brush with melted butter; sprinkle with optional seasonings.
3. Bake to Golden Perfection
- Bake 25–30 minutes, until biscuits are deep golden and filling is bubbly.
