Yes, there is a way for everyone to enjoy this mushroom shepherd’s pie. So, it’s time to read about the actual recipe.
How to Make Mushroom Shepherd’s Pie
- Sauté the onions. They should begin caramelizing so that they are deliciously sweetened and fragrant. Side note: There is nothing better than the aroma of onions being cooked. It’s half of the reason you need to be in the kitchen.
- Brown the mushrooms. These mushrooms add so much flavor to your dish. Even if you are making this dish vegetarian, they still pack the umami flavor.
- Garlic. A good recipe shouldn’t be complete without a generous amount of garlic. Don’t you agree?
- Tomato Paste. The natural sugars within the tomato paste will caramelize if you cook it for a few more minutes. This gives the dish a lot of extra flavors. This trick can be used whenever tomato paste is used.
- Worcestershire Sauce. This sauce is considered to be full of flavor. It is deep and salty with tons of umami from the anchovies. Side note: there are vegetarian options and there are a few substitutes for Whole30-ers.

After that, you can add the ground meat (or veggie meat) and the carrots and cook until it is no longer pink.
