Experience homestyle comfort at its finest with this easy chicken pot pie casserole. Juicy shredded chicken, garden-sweet peas, and tender carrots are enveloped in a velvety herb cream sauce, baked beneath a golden, fluffy crown of scratch-made cheddar buttermilk drop biscuits.
Traditional chicken pot pie requires tedious pie dough rolling and chilling that can turn weeknight dinner prep into an ordeal. This genius casserole skips the finicky double crust in favor of pillowy, tender cheddar drop biscuits that soak up the luscious sauce while developing an irresistibly crisp, buttery exterior in the oven.
Why You’ll Love This Recipe

Key Ingredients & Smart Swaps
- Cooked Shredded Chicken: Store-bought rotisserie chicken is an incredible weeknight shortcut. Cooked chicken breasts or thighs work equally well.
- The Mirepoix Trio: Diced yellow onions, carrots, and crisp celery build an aromatic base of traditional homestyle flavor.
- Rich Chicken Bone Broth & Cream: Simmering with flour builds a thick, velvety gravy without requiring canned condensed soups.
- Sharp Cheddar & Buttermilk: Freshly grated sharp cheddar cheese and tangy buttermilk give the drop biscuits their irresistible golden crust and flaky crumb.
Step-by-Step Cooking Walkthrough
1. Sauté the Mirepoix: Melt butter in a large skillet over medium heat. Cook diced onions, carrots, and celery for 6-8 minutes until tender-crisp.
2. Whisk the Velouté: Stir in garlic and flour, cooking for 2 minutes. Gradually whisk in chicken bone broth and heavy cream, simmering until thick, smooth, and bubbling.
3. Fold in Chicken & Peas: Stir shredded chicken, sweet peas, and fresh thyme into the sauce, then pour the mixture into your casserole dish.
4. Crown with Biscuits & Bake: Mix biscuit dough with shredded cheddar and drop generous mounds across the hot filling. Bake at 400°F (200°C) for 22 to 26 minutes until biscuits are deep golden and filling is bubbling vigorously.
3 Chef Secrets for Perfect Results
1. Drop Biscuits Onto Hot Filling: Pouring hot filling into the baking dish immediately before adding biscuit dough ensures the bottoms of the biscuits start cooking right away rather than absorbing liquid and turning gummy.
2. Shred Cheese From the Block: Pre-shredded cheese contains cellulose powder that prevents proper melting. Freshly shredded sharp cheddar melts seamlessly into the dough for maximum tenderness.
3. Let Rest Before Scooping: Allow the casserole to rest for 10 minutes out of the oven. This gives the velvety velouté sauce time to settle and cling to the vegetables and chicken.
What to Serve With Chicken Pot Pie Casserole
- Bright Garden Greens: A crisp arugula or mixed baby green salad dressed in a lemon Dijon vinaigrette provides a refreshing acidic counterpoint to the rich gravy.
- Roasted Autumn Veggies: Roasted green beans, maple balsamic Brussels sprouts, or honey-glazed baby carrots.
- Beverage Pairings: Pairs wonderfully with an unoaked Chardonnay, dry Pinot Grigio, or sparkling apple cider.
Storage, Freezing & Reheating Instructions
- Refrigeration: Cover cooled casserole tightly with foil or store in airtight containers in the refrigerator for up to 4 days.
- Oven Reheating: Reheat in a 350°F (175°C) oven for 15-20 minutes to keep biscuits crisp and warm the sauce through. Individual portions can be microwaved for 1-2 minutes.
- Freezing: Bake the filling without biscuits, freeze for up to 3 months, and thaw in the fridge before adding fresh biscuit dough and baking as directed.
Ingredients
Method
- Preheat oven to 400°F (200°C). Grease a 9×13-inch ceramic baking dish (or use an oven-safe deep cast iron skillet).
- In a large Dutch oven or skillet over medium heat, melt 4 tablespoons of butter. Add diced onion, carrots, and celery. Sauté for 6 to 8 minutes until vegetables begin to soften.
- Add minced garlic, fresh thyme, salt, and pepper; sauté for 1 minute until fragrant. Sprinkle flour over the vegetables and stir constantly for 2 minutes to cook out raw flour taste.
- Slowly whisk in chicken bone broth and heavy cream, whisking constantly to prevent lumps. Bring to a gentle simmer for 4 to 5 minutes until sauce thickens into a glossy velouté.
- Remove from heat and fold in the shredded chicken and frozen sweet peas. Pour the filling into the prepared baking dish.
- Prepare the biscuit dough: In a medium bowl, stir together biscuit mix, shredded cheddar cheese, minced parsley, and garlic powder. Add buttermilk and 2 tablespoons melted butter, stirring just until a soft, moist drop dough forms.
- Using a large cookie scoop or spoon, drop 6 to 8 generous mounds of biscuit dough evenly across the top of the hot chicken filling.
- Brush the biscuit tops with the remaining 2 tablespoons melted butter.
- Bake uncovered for 22 to 26 minutes until the biscuits are golden brown, cooked through in the center, and the creamy filling is bubbling around the edges.
- Let rest for 10 minutes before scooping into bowls to allow sauce to settle. Serve hot!
