Healthy mushroom pot pies with creamy cauliflower sauce and flaky crust, comfort food without the extra calories.
There’s just something comforting about warm, flaky pot pie fresh out of the oven, and this meatless version is sure to please the biggest of appetites. Mushrooms are the star of the show in these savory, healthy mushroom pot pies, with a vegetable filling smothered in a velvety, creamy cauliflower sauce and a tender, flaky crust.
I wanted to create a mushroom pot pie that had all the comfort of the classic version—but without the extra calories from butter, flour, and cream. David and I are always talking about food, and one day while we were on the road, I shared my idea for a lighter mushroom pot pie. I wanted a way to make the mushrooms rich and creamy without all the heavy ingredients. That’s when David suggested using a cauliflower cream sauce, BRILLIANT!
Perfect for Meatless Monday, these pies are vegetable-forward, freezer-friendly, and fully customizable. Let’s make some!

- Prep veggies: Roast cauliflower, sauté onions and garlic, parboil potatoes, carrots, and celery.
- Make the sauce: Blend roasted cauliflower with stock and seasonings until smooth and creamy.
- Cook mushrooms: Sauté until tender, then combine with veggies and sauce.
- Assemble pies: Spoon the filling into ramekins or a pie dish, top with the crust, and seal the edges.
- Bake: Cook until golden and flaky; let cool slightly before serving.
Make-Ahead & Freezing Instructions
These healthy mushroom pot pies are perfect for making ahead. Extra filling can be stored in a freezer-safe bag and frozen for later use. Thaw and reheat the filling in a saucepan, adjusting the consistency as needed by simmering to thicken or adding a small amount of vegetable broth to thin. Spoon into ramekins, top with pastry, and bake as directed.
Fully assembled pot pies can also be frozen in the ramekins before adding egg wash. Cover with foil and freeze for up to two months. Bake from frozen at 400 degrees F for 30 minutes covered, then uncover and bake another 30 minutes, or until golden brown.
Tips and Tricks
- Roast the cauliflower to remove excess moisture and thicken the sauce.
- Cook the mushrooms until browned to build flavor and prevent a watery filling.
- Add stock slowly when blending to control the sauce consistency.
- Let the filling cool slightly before assembling to help the crust bake up flaky.
- Vent the crust so steam can escape and prevent sogginess.

Healthy Mushroom Pot Pies With Cauliflower Sauce
Ingredients
- 1 large head cauliflower
- 4 tablespoons extra-virgin olive oil divided
- 2 cups sweet onions
- 2 cloves garlic chopped
- 4 sprigs fresh thyme
- 2 cups vegetable stock
- salt and fresh cracked black pepper to taste
- 1 cup carrots chopped into bite-size pieces
- 1 cup celery chopped into bite-size pieces
- 1 cup russet potato chopped into bite-size pieces
- 16 ounces Portobello mushrooms quartered
- 1 cup peas frozen
- 2 sheets store-bought pie crust or sheets of puff pastry
Instructions
- Preheat Oven to 400 degrees F.
- Cut the cauliflower into florets; toss on a large rimmed baking sheet with 2 tablespoons of the olive oil; season with kosher salt and freshly ground black pepper. Roast, tossing occasionally, until almost tender, 30 to 35 minutes. Set aside until needed.
- Meanwhile, in a large heavy pot or Dutch oven, heat the remaining olive oil. When the oil is hot, add the onions and thyme; saute over medium-low heat for 15 to 20 minutes, until translucent. Add the garlic and saute for about 2 to 3 more minutes. Turn off the heat and remove the sprigs of thyme.
- While the cauliflower and onions cook, parboil the potatoes, carrots, and celery by adding them to In a medium saucepan with cold water to barely cover. Cover and bring to a boil over high heat. Reduce the heat to medium; cook, covered, for about 10 to 15 minutes or until you can easily pierce the potatoes with a fork. Drain the potatoes carrots and celery in a colander.
- Using the same saucepan used to parboil the vegetables, heat the vegetable stock, but do not boil. Add the roasted cauliflower and half of the cooked onions to a food processor or blender. Pulse several times, then gradually add about ½ cup of the vegetable broth at a time to the cauliflower, scraping the sides as needed, until the cauliflower becomes a smooth puree.
- Remember, you don’t want to make it too watery, so it is better to add small amounts of the vegetable broth at a time. The longer you blend, the more silky and smooth the sauce becomes. Add more liquid if your sauce is too thick. When you reach the desired consistency, taste and season with salt, pepper, to taste.
- Add the mushrooms to the remaining onions in the heavy pot or Dutch oven over medium-low heat. Cook, stirring occasionally until the mushrooms are tender. Add the potatoes, carrots, celery, and carefully pour the cauliflower sauce into the pot with the vegetables. Sir in the peas and heat through; about 5 to 7 minutes. Turn off heat.
- Roll out the pie crust or puff pastry, place the ramekins on the sheet of pastry dough, so that there is about a 1-inch parameter around each ramekin. Using a knife, cut circles or squares large enough to fit over the ramekins.
- Spoon the mushroom filling into each of the ramekins, cover the top of the ramekin completely folding the dough over the edges pressing it against the ramekin for each.
- Using a fork, pierce the top of each pot pie, so that the steam will escape without making the crust rise.
- For a prettier crust, I like to brush the dough with egg wash, (1 egg + 2 tablespoons water, beaten) on top of the crust to make them golden brown, when baked, but this step is completely optional.
- Place the ramekins on a baking sheet and into a 400 degree F oven. Bake for 20 to 25 minutes, or until the tops are golden brown, and/or puffy if using puff pastry.
- Cool 10 minutes before serving and enjoy!

- Vent the crust so steam can escape and prevent sogginess.
- Freeze filling: Store extra filling in a freezer-safe bag. Thaw and reheat in a saucepan, adjusting thickness with broth if needed.
- Freeze assembled pies: Freeze unbaked pot pies in ramekins (no egg wash) and cover them for up to 2 months.
- Bake from frozen: Bake at 400 degrees F for 30 minutes covered, then uncover and bake 25–30 minutes until golden.
- Reheat refrigerated pies: Warm at 350 degrees F for 20–25 minutes, uncovering for the last few minutes to crisp the crust.
- Microwave tip: Reheat filling only in short intervals; avoid microwaving assembled pies to prevent soggy crusts.
