Regular button mushrooms are the best mushrooms to use when making stuffed mushrooms. A wide variety of ingredients can be used for the stuffing, including breadcrumbs, cheese, veggies, meat, or a combination of these ingredients.
Different ingredients affect the freezing possibilities of stuffed mushrooms, with some ingredients giving better results than others.
Always freeze stuffed mushrooms when they’re as fresh as possible. Mushrooms are good for only a few days before they start to bruise, so freeze your stuffed mushrooms as soon as you can!
Can Stuffed Mushrooms Be Frozen?
Yes, stuffed mushrooms can be frozen if they are prepared correctly. Freezing raw stuffed mushrooms has a better outcome than freezing them cooked.
Mushrooms stuffed with breadcrumbs freeze more successfully than mushrooms stuffed with meat-based fillings because the mushrooms absorb moisture from the meat and become soggy when defrosted.
Freezing Stuffed Mushrooms (Step-by-Step Instructions)
Before freezing stuffed mushrooms, make sure that you have enough space in the freezer to accommodate a flat baking sheet. A baking sheet and parchment paper are needed for freezing stuffed mushrooms.
How to Freeze Stuffed Mushrooms
Use the following method for freezing both cooked and uncooked stuffed mushrooms:
Step One: Prepare the Mushrooms
Wipe the mushrooms clean with a soft, damp cloth. Excess water makes mushrooms soggy, so don’t rinse or soak them in water. Prepare the mushrooms according to your recipe.
If you want to freeze cooked stuffed mushrooms, allow the mushrooms to cool fully before freezing them.
Step Two: Prepare the Baking Tray
Line a baking tray with parchment paper.
Step Three: Place the Mushrooms on the Tray
Arrange the mushrooms on a parchment paper-lined baking tray. Leave at least ½ an inch between each mushroom to prevent them from sticking together.
Step Four: Place the Mushrooms in the Freezer
Place the tray of mushrooms in the freezer for two to three hours, or until the mushrooms are completely frozen, before transferring them to a closed storage container in the freezer, where they can be stored for up to three months.
Can You Freeze Stuffed Mushrooms Before Baking?
Yes, you can freeze stuffed mushrooms before baking them. Raw-frozen stuffed mushrooms are better than mushrooms that were frozen after being cooked. Mushrooms often become soft when cooked a second time after having been pre-cooked then frozen.
However, mushrooms with certain fillings, like meat and seafood, should be cooked before they’re put in the freezer because the mushrooms absorb the natural moisture in these raw meat ingredients, resulting in soggy stuffed mushrooms once thawed.
How to Cook Frozen Stuffed Mushrooms
Cook frozen stuffed mushrooms straight from the freezer, without defrosting them first. Here is a list of the equipment needed:
- Baking tray
- Parchment paper
- Pastry brush
- Olive oil (optional)
Follow these easy steps to bake frozen stuffed mushrooms in the oven:
- Preheat the oven to 350°F
- Line a baking tray with parchment paper
- Arrange the frozen stuffed mushrooms on the baking tray, stuffing side up, with at least ½ an inch between the mushrooms to prevent them from sticking together
- Brush the mushrooms lightly with olive oil if you want them to have brown, crispy tops
- Place the tray in the preheated oven and bake for seven to ten minutes, or until the mushrooms are nicely browned on top
- Remove from the oven and serve immediately
To easily thaw and reheat stuffed mushrooms in the microwave that have been pre-cooked, place the mushrooms on a piece of paper towel on a microwave-safe plate, spaced at least ½ an inch apart. Microwave on medium heat for one to two minutes, checking every thirty seconds to see if they are hot.
Remove the mushrooms from the microwave and leave them to stand for one minute before eating, to avoid “hot spots” and to allow the heat to spread evenly through the stuffed mushrooms.
Don’t refreeze microwaved, stuffed mushroom leftovers because the texture deteriorates, and bacteria easily multiply, making the stuffed mushrooms unsafe to eat.
Heating frozen stuffed mushrooms in a microwave doesn’t give the same crispy result as cooking them in an oven gives, even when the mushrooms have been cooked before being frozen. Additionally, cooking raw, frozen stuffed mushrooms in a microwave doesn’t work well because the mushrooms become soggy.
Storing Frozen Stuffed Mushrooms
To store frozen stuffed mushrooms, you need:
- Ziplock bags or a plastic container with an airtight seal
- Parchment paper
Arrange the pre, baking tray-frozen stuffed mushrooms in single layers in the ziplock bag or plastic container, with a piece of parchment paper between the layers so that the mushrooms don’t stick together. Seal the bags or containers tightly. If using ziplock bags, remove as much air as possible from the bags.
Place the mushrooms in the freezer. Don’t place anything heavy on top of the ziplock bags, to avoid crushing the mushrooms. Store stuffed mushrooms in the freezer for up to three months.
