Ingredients You’ll Need

24 oz whole milk cottage cheese: A creamy base that thickens the filling, making it delightful and comforting. If you need a low-fat version, low-fat cottage cheese works well here.
2 Tbsp cornstarch: This ingredient helps thicken the sauce. If you don’t have cornstarch, try using all-purpose flour, but note that it may require longer to thicken if you go that route.
1 12-oz bag frozen peas and carrots: These veggies add color and nutrition without the prep time. Fresh produce could be used, but would require a bit longer cooking time.
2 15-oz cans chickpeas, drained: They provide protein and heartiness to the dish. If you prefer non-canned options, you might cook dried chickpeas, but be prepared for extra time.
1 15-oz can corn, drained: Corn adds a sweet crunch. You can swap it for fresh corn in season for a lovely, fresh taste.
2 cloves garlic, minced: For that aromatic flavor that makes everything taste so much better. Fresh garlic is best, but garlic powder is a quicker substitute.
1 tsp vegetable bouillon base (we used Better Than Bouillon): This adds depth of flavor. If yours is unavailable, a cup of vegetable broth can be used instead; just be mindful of adjusting the liquid in the recipe.
1 tsp each dried thyme and parsley: These herbs enhance the flavor profile of the pot pie. Fresh herbs could be used in half the amounts; just make sure to adjust to taste.
½ tsp onion powder: This provides an allium flavor without the need to chop onions. You can leave it out if you prefer a milder flavor.
¼ tsp each salt and pepper: Essential for seasoning. Adjust according to your taste preferences!
1 16-oz can refrigerated biscuits (Pillsbury Grands recommended): These make a perfectly flaky topping. If you’re looking for a healthier alternative, feel free to use whole wheat biscuits, or even a homemade biscuit dough.

How to Make Vegetable Pot Pie Casserole

Preheat your oven: Set the oven to 400°F (204°C) to prepare for cooking.
Blend the base: In a countertop or handheld blender, combine 24 oz of whole milk cottage cheese with 2 Tbsp of cornstarch until the mixture is smooth and creamy.
Combine the filling: In a 9×13 inch casserole dish, add the blended cottage cheese, a 12-oz bag of frozen peas and carrots, two 15-oz cans of drained chickpeas, one 15-oz can of drained corn, two minced cloves of garlic, 1 tsp of vegetable bouillon base, 1 tsp each of dried thyme and parsley, ½ tsp of onion powder, and ¼ tsp each of salt and pepper. Stir everything together until evenly mixed.
Start heating the filling: Place the dish in the oven and bake for 15 minutes. After that, give the mixture a good stir before proceeding.
Top with biscuits: Open the 16-oz can of refrigerated biscuits and cut each biscuit into about four pieces. Evenly arrange these biscuit pieces over the sauce in a single layer, ensuring they don’t sink into the filling. Optional: Lightly spray the top with vegetable oil, which helps the biscuits turn golden brown.
Bake to perfection: Lower the oven temperature to 350°F (176°C). Return the dish to the oven and bake for an additional 20 to 30 minutes, or until the biscuits are golden brown and the sauce is bubbling cheerfully at the edges of the pan. Serve warm and enjoy every bite!

Storing & Reheating

Allow any leftovers to cool completely before placing them in an airtight container. Refrigerate for up to 3 days to keep everything fresh. If you need longer storage, you can freeze the casserole for up to three months. To reheat, simply place in your oven at 350°F (176°C) for about 20 minutes or until hot throughout. Keep in mind that the biscuits might not stay as crisp after freezing, but if you do feel like they need a little refresh, a quick run in the toaster oven could revitalize them!

Chef’s Helpful Tips

Watch for overcooking: Keep an eye on the biscuits, as you don’t want them to burn. If they brown too quickly, you can tent the casserole with aluminum foil.
Ingredient temperature matters: Using room temperature cottage cheese can help it blend smoother.
Timing: If you’re short on time, prepare the filling in advance and simply add the biscuits before baking.
Adjust flavors: Don’t be shy with seasoning—taste the filling before topping with biscuits and adjust salt and spices as needed.
Make it ahead: You can assemble the casserole a day ahead without adding biscuits, cover it, and refrigerate until ready to bake.

Creamy, satisfying, and quick to prepare, this dish really has it all. Plus, it’s a fantastic vehicle for any vegetables you want to incorporate. Feel free to swap in whatever’s in season or what’s sitting in your pantry!

Recipe FAQs

Can I use fresh vegetables instead of frozen?

Absolutely! Fresh vegetables can give your casserole an even more vibrant flavor. Just make sure to chop and cook them slightly before mixing them in to soften them a bit.

Can I make this casserole gluten-free?

Yes, you can easily make this dish gluten-free by using gluten-free refrigerated biscuits. Just check the packaging to ensure they are certified gluten-free before using.

Is there a vegan option for this recipe?

It’s certainly possible! To make a vegan version, you can substitute the cottage cheese with a creamy vegan alternative, like blended silken tofu or a nut-based cheese. Additionally, opt for a plant-based biscuit and substitute the veggie bouillon with nutritional yeast or a homemade broth.

How can I switch up the flavors in the casserole?

Feel free to add different herbs or spices based on your preference! A pinch of smoked paprika or curry powder can add a fantastic twist. You could also throw in some fresh spinach or kale for an added health boost. Don’t hesitate to experiment and make it your own!
