How to Make Biscuit Vegetable Pot Pie Casserole Recipe
Step 1: Prepare the Biscuit Dough
Start by whisking together the flour, baking powder, and salt either by hand or in a food processor. I always cube my butter and keep it cold—this is the trick I discovered to get those flaky biscuit layers. Cut or pulse the butter into the dry ingredients until coarse crumbs appear. Then mix in 1 cup of milk (hold back some for brushing later). The dough should come together shaggy and slightly sticky; trust the process. If it feels too dry, add a touch more milk, or a dash more flour if too wet. Shape the dough into 8 or 9 discs about an inch thick—don’t stress about being perfect! I keep my hands dusted with flour and arrange them on a lined plate to chill while making the filling.
Step 2: Cook the Vegetable Filling
Melt butter in a large oven-safe skillet over medium heat (I love using my trusty 12-inch skillet for this). Add onion, carrots, celery, mushrooms, and garlic and cook for about 5 minutes until the veggies soften and release their juices. Stir in the flour and season with salt, pepper, and thyme—this step is key to thickening the filling like a creamy pot pie base. Gradually whisk in vegetable broth and ½ cup milk. Simmer for 7 to 9 minutes until it thickens into a luscious, hearty sauce. Stir in your mixed vegetables and parsley, taste, and adjust seasoning as needed. Once done, remove from heat and let cool slightly while preheating your oven.
Step 3: Assemble and Bake
Grease a 2.5- to 3-quart baking dish or a deep 9-inch pie dish and pour the vegetable filling in evenly. Arrange the chilled biscuit discs on top, squeezing them together to cover the filling completely. Brush the biscuit tops with the reserved milk to encourage a golden, glossy finish. Bake at 400°F (204°C) for 25 minutes, then turn up the oven to 425°F (218°C) and bake for an additional 5 to 6 minutes until the biscuits are beautifully golden. Let it rest for 5 minutes before serving so the filling can set slightly—it makes scooping a dream!
Pro Tips for Making Biscuit Vegetable Pot Pie Casserole Recipe
- Keep Butter Cold: Cold butter in the biscuit dough is your secret weapon for flaky, tender biscuits every time.
- Don’t Overmix Dough: Mix just until combined to avoid tough biscuits—a little shaggy and sticky is good!
- Use Oven-Safe Skillet: Cooking the filling in an oven-safe skillet saves a transfer step and helps flavor meld beautifully.
- Rest Before Serving: Let the casserole cool slightly so the filling firms — it makes serving easier and cleaner.
How to Serve Biscuit Vegetable Pot Pie Casserole Recipe
Garnishes
I love topping this pot pie casserole with a sprinkle of fresh parsley right before serving to brighten the dish with color and fresh herb flavor. Sometimes I add a few cracks of black pepper or a sprinkle of grated Parmesan cheese for an extra touch of indulgence. It’s those little details that really make the dish feel special.
Side Dishes
Since the casserole is filling on its own, I like pairing it with light sides like a crisp green salad or steamed green beans tossed with lemon and olive oil. Roasted root vegetables also work well if you’re looking for a heartier meal, but honestly, this dish is a comforting one-pan dinner that shines as the star.
Creative Ways to Present
For holiday gatherings or special occasions, I’ve baked this casserole in individual ramekins for personal servings, which feels extra cozy and fancy. You can also arrange the biscuits in fun shapes or sprinkle the top with shredded cheese before baking for a crispy, cheesy crust. Playing with presentation is a fun way to make this homely dish stand out!
Make Ahead and Storage
Storing Leftovers
I store leftovers covered tightly in an airtight container in the fridge, and they keep well for up to 5 days. The filling stays flavorful and the biscuits remain tender—just be sure to keep everything sealed to avoid drying out. It’s perfect for packing lunches or quick weeknight dinners.
Freezing
Freezing this biscuit vegetable pot pie casserole works like a charm, which I love for meal prep. I freeze it unbaked in a foil pan and then bake straight from frozen—just add extra baking time and keep an eye on the biscuit browning. Or freeze baked portions in individual containers for quick reheating later. Just be sure to cool completely before freezing to maintain texture.
Reheating
To reheat leftovers, I pop the casserole or individual servings into a 350°F oven for about 15-20 minutes, covered with foil to keep moisture in. For a crispier biscuit topping, remove the foil during the last 5 minutes of baking. You can also microwave leftovers for convenience, but I prefer the oven method to retain that fresh-baked texture.
FAQs
-
Can I use store-bought biscuits for this Biscuit Vegetable Pot Pie Casserole Recipe?
Absolutely! Store-bought biscuits can save time and still turn out delicious. Just make sure to choose a flaky variety and bake according to package instructions, adjusting for the casserole’s baking times. Keep an eye on the crust so it doesn’t overcook.
-
What vegetables work best in this pot pie casserole?
I recommend a mix of carrots, celery, mushrooms, peas, and broccoli or cauliflower florets for a balanced flavor and texture. Feel free to add or swap in seasonal vegetables like sweet potatoes, green beans, or zucchini to suit your preference or what’s in your fridge.
-
Can I make this recipe gluten-free?
Yes, you can substitute the all-purpose flour with a gluten-free flour blend suitable for baking. Just note that you may need to adjust the amount slightly to get the right biscuit dough consistency and ensure your vegetable broth is gluten-free as well.
-
How do I prevent the biscuit topping from getting soggy?
Using cold butter and properly chilling the biscuit dough before adding it to the filling helps create a crust that stays flaky. Also, baking the casserole at the right temperature and finishing with a higher heat for a few minutes gives the biscuits a beautiful golden, slightly crisp top that resists sogginess.

Instructions
- Make the biscuit topping: Whisk the flour, baking powder, and salt together in a large bowl or use a food processor. Add the cold butter and cut into the dry ingredients with a pastry cutter or pulse several times in the processor until coarse crumbs form. Add 1 cup (240ml) milk (reserve the rest for brushing), and stir or pulse until dough comes together. Adjust with additional milk or flour if needed. With floured hands, shape dough into 8 or 9 one-inch-thick discs. Place on a lined plate or baking pan, cover tightly, and refrigerate until ready to use or for up to 2 days.
- Prepare the filling: Melt butter in a large skillet or oven-safe pan over medium heat. Add diced onion, carrots, celery, mushrooms, and minced garlic. Cook, stirring occasionally, for 5 minutes until vegetables soften and release liquid. Stir in flour, salt, pepper, and thyme until the flour absorbs all the liquid. Add vegetable broth and 1/2 cup (120ml) milk, then simmer for 7–9 minutes until mixture thickens into a soup-like consistency. Stir in mixed vegetables and parsley, then remove from heat. Adjust seasoning as desired and let cool for 5 minutes.
- Preheat the oven: While filling cools, preheat oven to 400°F (204°C).
- Assemble the casserole: Pour the filling into a greased 2.5- or 3-quart baking dish or a 9-inch deep pie dish. Arrange chilled biscuit discs tightly on top of the filling. Brush the biscuit tops with the remaining 2 Tablespoons (30ml) milk.
- Bake the pot pie: Bake at 400°F for 25 minutes. Then increase oven temperature to 425°F (218°C) and bake for an additional 5–6 minutes until biscuits are golden brown on top.

Notes
- You can use any combination of mixed vegetables such as frozen peas, broccoli, cauliflower florets, or other preferred vegetables in the filling.
- Ensure the biscuit dough is slightly sticky but manageable with floured hands to achieve tender biscuits.
- The biscuit size and number may vary depending on the baking dish used; adjust accordingly to fit on top of the filling.
- For richer flavor, use fresh herbs when possible, but dried thyme and parsley work well too.
- Leftover pot pie can be reheated on the stovetop or in a microwave until warmed through.
