Ingredients for Cheesy Stuffed Mushrooms
Gathering your stuff is half the battle. Get everything out before you start. It just makes the whole process smoother.
Produce
24 medium button or crimini mushrooms. These are your base. Get them fresh. Don’t use canned. Ever.
2 cloves garlic (minced). Fresh garlic always. You want that punch.
2 tsp chopped fresh sage. Don’t skip the fresh. It makes a difference.
Dairy & Fats
2 tbsp salted butter. Good quality butter, please. It is a flavor carrier.
3 ounces cream cheese (softened). Take it out of the fridge early. Cold cream cheese is a pain to mix.
6 ounces sharp white cheddar (grated). Grating your own cheddar is always better than pre-shredded. It melts better and tastes better.
How to make Keto Stuffed Mushrooms
No need to overthink this. It is pretty simple cooking. Stick to the steps, and you will have these delicious Keto Cheese Stuffed Mushrooms on the table in no time.
Prep the Mushrooms
First things first. You have to clean those mushrooms. Don’t drown them. Get a damp cloth and wipe off any dirt.
Snap off the stems. Finely dice those stems. Keep the caps whole to act as your little boats for the filling.
Build the Filling
Melt the butter in a medium skillet over medium heat. Add the diced mushroom stems and the minced garlic. Sautรฉ until tender.
Stir in the fresh sage. Season with a pinch of salt and pepper. Take off the heat and let cool for five minutes.
Stuff and Bake
Combine the softened cream cheese, grated sharp white cheddar, and cooled mushroom mixture. Spoon the mixture into each cap.
Bake at 350ยบF for 15 to 20 minutes until bubbling. Let them sit for 10 minutes before serving.
Tips for the best Cheesy Stuffed Mushrooms
Don’t wash your mushrooms under running water. A damp cloth keeps them from getting watery when they bake.
Grating your own cheese makes a huge difference in the melt. If you need a main course to pair with these, try a hearty beef taco bake to round out your meal.
Don’t overfill the caps, but don’t underfill. You want a good, generous mound.
Storage and Reheating Instructions
Pop leftovers in an airtight container. They will last in the fridge for up to three days.
To reheat, use a moderate oven at 300ยบF for about 10-15 minutes. You can also learn about the nutritional value of crimini mushrooms to see why these are a smart choice.
These Keto Cheese Stuffed Mushrooms are best fresh, but leftovers are a solid second.
