Ingredients You’ll Need

Each ingredient in this Biscuit Vegetable Pot Pie Casserole Recipe plays a role in balancing flavors and textures — from the flaky biscuits to the savory veggie filling. A few simple pantry staples come together beautifully, but quality butter and fresh herbs make all the difference.

• All-purpose flour: I use spooned and leveled flour for the biscuits to get that perfect light texture.
• Baking powder: Yes, a full tablespoon! It’s the secret to super fluffy biscuits.
• Unsalted butter: Make sure it’s cold and cubed for the biscuit dough, and also for the filling — butter adds richness and depth.
• Whole milk: Divided for the biscuit dough and the filling; it makes everything tender and creamy.
• Yellow onion: Adds sweetness and a subtle depth to the filling.
• Carrots: Freshly diced or sliced carrots add a nice crunch and color.
• Celery: Brings that classic pot pie flavor base with its slight bitterness and crunch.
• Mushrooms: I love how they absorb flavors and give the filling an earthy nuance.
• Garlic: Minced for that fresh punch of flavor in the filling.
• Salt & Pepper: To season the filling perfectly — don’t skip seasoning!
• Fresh thyme: Whether fresh or dried, thyme infuses a lovely aroma and herbal note.
• Vegetable broth: This is the heart of the filling’s savory base — use a good quality broth for best flavor.
• Mixed vegetables: I often use frozen peas, broccoli, and cauliflower to add texture and nutrition.
• Fresh parsley: Chopped and stirred in at the end for a fresh pop of color and brightness.

Variations

If you like playing around with flavors, this biscuit vegetable pot pie casserole recipe is a fantastic base for all sorts of tweaks. I often customize it depending on the season or what’s in my fridge — it’s super forgiving.

• Adding Protein: I’ve added shredded rotisserie chicken before — it made the casserole even heartier without much effort.
• Herb Swap: Experiment with rosemary or sage instead of thyme for a different aromatic twist.
• Dairy-Free: Use a plant-based milk and dairy-free butter substitutes in both the biscuit and filling to make it vegan-friendly.
• Seasonal Veggies: Swap out carrots and celery for sweet potatoes or butternut squash in the fall — it’s delicious!

How to Make Biscuit Vegetable Pot Pie Casserole Recipe

Step 1: Make the biscuit topping dough

Start by whisking the flour, baking powder, and salt together in a large bowl or pulse them in a food processor—whichever you prefer. Add the cold, cubed butter and cut it into the flour until you get a coarse crumb texture. This step is crucial because those little buttery bits create that flaky biscuit texture you’re aiming for. Next, pour in 1 cup of milk (reserve the rest for later), and gently stir until the dough just comes together — it’s okay if it looks a little shaggy or sticky. If it seems too dry, add a tablespoon more milk; if too wet, sprinkle in a little more flour. Once mixed, with floured hands, shape the dough into eight or nine discs about 1 inch thick. Don’t stress if they aren’t perfect — rustic is charming here! Place them on a lined baking sheet, cover tightly, and refrigerate until ready to bake.

Step 2: Cook the vegetable filling

Melt butter over medium heat in a large oven-safe skillet or pot. Add diced onion, carrots, celery, mushrooms, and minced garlic. Stir every so often for about 5 minutes until the veggies soften and start releasing their juices. Then sprinkle in the flour, salt, pepper, and thyme — the flour will soak up the liquid and thicken the mixture, so keep stirring to avoid lumps. Gradually pour in the vegetable broth and half a cup of milk, stirring as it simmers until you get a thick, creamy sauce—about 7 to 9 minutes. Finally, stir in your mixed vegetables and parsley, then taste and adjust seasoning as needed. Let it cool a bit while you preheat your oven.

Step 3: Assemble and bake

Grease your baking dish or oven-safe skillet generously. Pour the lush vegetable filling evenly inside. Now, take your chilled biscuit discs and arrange them on top — you can gently squeeze them together if necessary. Brush the tops lightly with the remaining milk; this little touch helps them brown beautifully and get that golden crust. Bake at 400°F for 25 minutes, then crank the heat up to 425°F and bake for another 5-6 minutes until those biscuits are perfect golden beauties. Let the casserole rest for 5 minutes before serving so everything sets nicely.

How to Serve Biscuit Vegetable Pot Pie Casserole Recipe

Garnishes

I like to sprinkle a little extra fresh parsley on top right before serving — it adds brightness and a fresh look. Sometimes a shake of smoked paprika or a pinch of grated Parmesan on the biscuits lifts the flavors beautifully, especially if you want a little extra flair.

Side Dishes

This casserole is quite the star, so I usually keep sides simple. A crisp green salad with a light vinaigrette balances the richness. You’d also enjoy it with roasted Brussels sprouts or garlic steamed green beans to add a different texture and freshness.

Creative Ways to Present

For special occasions, I’ve made this casserole in individual ramekins topped with biscuit rounds for personal servings — it makes the presentation feel extra cozy and charming. You can even sprinkle a little cheese over the biscuits before baking to make it a savory treat everyone loves.

Make Ahead and Storage

Storing Leftovers

Leftovers store beautifully in an airtight container in the fridge for up to five days. When I reheat, I cover it lightly with foil to keep the casserole moist while warming.

Freezing

You can freeze this casserole before baking for up to 3 months. Just assemble it in a freezer-safe dish, wrap tightly in foil and plastic wrap, and label it. Thaw overnight in the fridge before baking as usual.

Reheating

I find reheating in the oven at 350°F covered with foil works best to keep the biscuits tender while warming the filling through. About 20–25 minutes should do the trick. Avoid microwaving if you want to maintain that fresh-baked biscuit texture.
