Vegetarian Pot Pie Recipe with vegetables and mushroom

I’ve always loved comfort food, the kind that warms the house and fills the kitchen with an irresistible aroma (especially these last few days when it’s been very cold in Grenoble, almost snowy…), and this Vegetarian Pot Pie recipe is one of them! Often made with chicken, I opted for a vegetarian version here, but nothing prevents you from adding a touch of meat, for example with leftover roast chicken.
What I love about this pie is its perfect balance between the crispness of a beautiful golden crust and the tenderness of the vegetables, all topped with an absolutely divine creamy sauce. Plus, it lends itself to all sorts of variations: you’re free to adapt the vegetables according to your tastes or the season.

I chose a selection of winter vegetables, but if you don’t like celery for example, no worries, you can leave it out or replace it. You can also add a handful of spinach for a touch of greenery, or even a few pieces of sweet potato for a slightly sweet note. And if you’re a cheese lover, a touch of grated cheese, fresh goat cheese, or Parmesan to the filling will add an extra touch.
By the way, a little anecdote: for this tart, I had planned to add frozen peas. Except… I completely forgot! I only realized it after putting the tart in the oven. So, I decided to make a second one, just to make up for it… and believe me, we didn’t need to be asked twice to eat it all! But it’s the first one you see in the photo… 😉

But the real surprise was the children’s reaction. I don’t know why, but I had some doubts about their enthusiasm for this recipe, and yet, they loved it! So much so that they asked for more… and now, they ask for it regularly.
So, if you’re looking for a simple, comforting meal idea that’s adaptable to your tastes, this pie is for you. With its golden, crispy pastry and smooth, flavorful filling, it’s perfect for a dinner with family or friends.
You can serve this vegetarian pie with a nice seasonal salad, such as batavia, lettuce, lamb’s lettuce, or even endives.
Get cooking! And don’t forget the peas… or not! 😉
