Ingredients

• 4 Tbsp butter
• 3 medium carrots, diced (about 1½ cups)
• 3 stalks celery, diced (about 1½ cups)
• 1 large yellow onion, diced (about 1½ cups)
• 1 tsp fresh thyme, chopped
• 1 tsp kosher salt, divided
• ½ tsp freshly ground black pepper
• 4 Tbsp all-purpose flour
• 2 cups whole milk
• 1 cup low-sodium chicken broth
• 1 Tbsp Dijon mustard
• ½ tsp garlic powder
• 4 cups cooked shredded chicken
• 1 cup frozen peas
• 1 (16.3-ounce) tube biscuit dough
• Optional but delicious: a pinch of smoked paprika, extra thyme, or a splash of cream for added richness.

How to Make the Best STEP-BY-STEP

1. Preheat the oven. Set your oven to 400°F (200°C). Grease a 9×13-inch baking dish.
2. Sauté the vegetables. In a large skillet over medium heat, melt the butter. Add diced carrots, celery, and onion with ½ teaspoon kosher salt and the black pepper. Cook, stirring occasionally, until the vegetables soften and the onions turn translucent, 7–9 minutes. Stir in the chopped thyme during the last minute to bloom the flavor.
3. Make the roux. Sprinkle the flour over the vegetables. Stir constantly for 1–2 minutes to create a blond roux that removes the raw flour taste.
4. Whisk in liquids. Slowly pour in the milk and chicken broth, whisking continuously to avoid lumps. Add the Dijon mustard and garlic powder. Bring to a gentle simmer. Cook 3–5 minutes, stirring, until the sauce thickens into a gravy that coats the back of a spoon.
5. Season and add chicken. Taste and adjust with the remaining ½ teaspoon kosher salt if needed. Fold in the shredded chicken and frozen peas until evenly combined and warmed through.
6. Transfer to the dish. Pour the creamy chicken mixture into the prepared baking dish and spread into an even layer.
7. Add the biscuits. Open the tube of biscuit dough. For even baking and more surface area, cut each biscuit into quarters. Scatter the pieces evenly over the filling, leaving small gaps so steam can escape. For extra color, lightly brush the biscuit tops with milk or melted butter (optional).
8. Bake. Place the dish on the center rack and bake 15–20 minutes, until the biscuits are puffed and deeply golden and the filling is bubbling around the edges. If the tops brown too quickly, tent loosely with foil for the last few minutes.
9. Rest and serve. Let the casserole rest 5–10 minutes to set. Garnish with more thyme if you like, then scoop and serve hot.

Tip: For ultra-golden biscuits, start the bake on the lower-middle rack for the first 10 minutes, then move to the middle rack to finish.

Healthier Alternatives

• Lighten the sauce: Use 2% milk instead of whole milk and reduce butter to 2–3 Tbsp. Stir in ¼ cup plain Greek yogurt off heat for creaminess.
• Veggie boost: Add 1 cup diced mushrooms or 1 cup cauliflower florets with the mirepoix to increase volume and fiber.
• Lean chicken: Use mostly chicken breast or rotisserie breast meat to reduce fat.
• Whole-grain topper: Swap in whole-wheat biscuit dough for more fiber.
• Dairy-free: Use olive oil or vegan butter, unsweetened almond or oat milk, and thicken with 2 Tbsp cornstarch slurry added to the simmering broth.
• Gluten-free: Replace flour with a 1:1 gluten-free flour blend or 1½ Tbsp cornstarch and use a gluten-free biscuit dough or top with buttered, crumbled gluten-free crackers.
• Lower sodium: Choose low-sodium broth and adjust salt to taste at the end.

Serving Suggestions

• Fresh and crisp: Pair with a lemony arugula salad or simple mixed greens with vinaigrette to balance the richness.
• Vegetable sides: Roasted green beans, honey-glazed carrots, or garlicky sautéed kale.
• Comfort duo: Serve with cranberry sauce or a quick apple slaw for sweet-tart contrast.
• Flavor finish: Sprinkle with chopped parsley or chives, or add a pinch of flaky sea salt just before serving.

Storing Tips & Make Ahead & Freeze Tips

• Refrigerate: Cool completely, cover, and refrigerate up to 3–4 days. Reheat at 350°F (175°C) until hot and biscuits re-crisp (about 20 minutes). Microwaving softens biscuits; for best texture, reheat in the oven or an air fryer.
• Make ahead: Assemble the filling up to 2 days ahead and refrigerate. When ready to bake, warm the filling on the stove, transfer to the dish, add biscuit dough, and bake. Avoid topping with biscuits until just before baking to prevent sogginess.
• Freeze (unbaked): Assemble the filling in a freezer-safe dish, cool, cover tightly, and freeze up to 3 months. Add biscuits just before baking. Bake from frozen at 375°F (190°C), covered with foil for 30–35 minutes, then uncover, add biscuits, and bake 20–25 minutes more until golden and bubbling.
• Freeze (baked): Cool completely, wrap tightly, and freeze up to 2 months. Reheat covered at 350°F until hot, then uncover to re-crisp the biscuits.

Common Mistakes to Avoid

• Runny filling: Cook the roux long enough and simmer the sauce until it thickens before adding chicken and peas.
• Soggy biscuits: Don’t add biscuits to cold filling; warm filling helps them bake and brown. Leave small gaps for steam to escape.
• Lumpy sauce: Add milk and broth slowly while whisking; keep the heat moderate.
• Undercooked vegetables: Soften the carrots and celery before making the roux for a tender bite.
• Over-salting: Use low-sodium broth and adjust salt at the end after tasting.
• Skipping the rest: Let the casserole sit 5–10 minutes post-bake so the filling sets.

Final Tips & Conclusion

For the absolute best texture and flavor, give the vegetables time to soften, whisk the sauce patiently, and bake until the biscuits are deeply golden. Cutting biscuits into quarters ensures more crispy edges and fewer doughy centers. A touch of Dijon brings brightness and complexity without stealing the show.
