Keto Stuffed Mushrooms
Sundried tomatoes are one of my favorite flavors. They pack so much flavor into a tiny package. If you’ve ever watched the Food Network you’ve probably heard the word umami being thrown around. Here’s what Wikipedia has to say:
How To Make Spinach Stuffed Mushrooms with Garlic
Start by preheating your oven. Then work at removing the stems from the mushrooms and cleaning them to ensure no dirt is on them.
In a bowl, you want to mix in the filling ingredients, and once well-combined spoon into the mushrooms. You want them to overflow a bit, as it will shrink down as mushrooms bake. Top with leftover mozzarella and bake until softened and cheese is golden brown.
What Kind Of Mushrooms Are Best For Keto Stuffed Mushrooms
I reach for smaller mushrooms. White button mushrooms or even cremini are a great variety of mushrooms for stuffed mushrooms. I have found that the white mushrooms offer a more mild flavor. If you were wanting to make more of entree style mushrooms you could reach for a portobello mushroom.
Best Way To Clean Mushrooms
Whenever you use mushrooms do not get them very wet. They get soggy. Instead, take a damp paper towel or washcloth and gently rub them clean.
Simply wet a paper towel and work at wiping away all the dirt on the mushrooms. You can also rinse in water, but just ensure you thoroughly dry them with a towel. If you soak the mushrooms it will break them down. Do a quick rinse and then pat them dry.
After you clean the mushrooms you will want to remove the stems. That way it offers a little nook for your spinach filling to go in.
Can You Freeze Spinach Stuffed Mushrooms
Unfortunately, mushrooms do not freeze well. But, you could prepare the filling and freeze that and then when ready to use thaw in the fridge and then prep mushrooms and fill as directed below. This is a way to speed up the prep time if you are serving these up for an appetizer for a crowd.
How Long To Cook Mushrooms with Garlic & Sun Dried Tomatoes
Spinach stuffed mushrooms can take anywhere from 20 to 25 minutes. But depending on the size of mushrooms you purchase can vary in cooking time. For example, if you bought larger mushrooms you will need to cook longer. Or if smaller you might only need to cook 15-20 minutes.
What Temperature Do You Cook Keto Stuffed Mushrooms
For my recipe, I have found that 400 degrees is a perfect temperature. This will help make toppings nice and golden brown and allow the mushrooms to cook and soften up.
Can I Pre-Make These Keto Stuffed Mushrooms
You are welcome to assemble your mushrooms in advance up to 6 hours. Then just wrap loosely and place in the fridge until you are ready to bake. Then just allow a few more minutes of cooking as it will need to warm up the pan and take the chill off the mushrooms before it begins baking.
Best Way To Reheat Mushrooms
I have found that reheating these mushrooms in the oven is the best for quality. Just take your chilled mushrooms and place them on a baking sheet and cook at 350 degrees. Cook for around five minutes and come check to see if they are warmed through. Heat until they are fully heated, and then serve.
You can opt for the microwave, I just find they offer a softer texture if they don't get heated in the oven. I think a toaster oven could work as well, I haven't tried it though.
