Ingredients
- 24 ounces Large Fresh Mushrooms I used white button mushrooms, but baby bellas would work too.
- ½ pound Corned Beef Cooked and diced. See Notes.
- ½ cup Sauerkraut Rinsed and Drained
- 2 - 3 tablespoons Avocado Oil Or Regular Olive Oil
- 1 cup Spanish Onion Diced. Approximately one half large onion. 120 grams
- 2 teaspoons Garlic (4 cloves) Minced
- 8 ounces Cream Cheese (1 package) Softened.
- ½ cup Provolone Cheese Shredded
- ¼ cup Gruyere Cheese Shredded
- ¼ cup Thousand Island Dressing
- 1 tablespoon Spicy Brown Mustard
- 1.5 teaspoons Dried Chives plus more for garnish
- ½ cup Green Onions (Optional) Thinly sliced.
Instructions
- Wipe 24 ounces Large Fresh Mushrooms with a damp paper towel or cloth to remove dirt. Remove the stems and scrape out the cap to make room for the filling. Dice the stems and other removed mushroom parts and set aside. Place the mushroom caps in a bowl or zip top bag and set aside.24 ounces Large Fresh Mushrooms
- Rinse and drain 1/2 cup Sauerkraut. Set aside.1/2 cup Sauerkraut
- Dice 1/2 pound Corned Beef (cooked). Set aside.1/2 pound Corned Beef
- Heat 1 - 2 tablespoons of oil in a large skillet over medium high heat. Sauté the onions until translucent. About 8 minutes. Add in 2 teaspoons Garlic (minced) and sauté for another 30 seconds.2 - 3 tablespoons Avocado Oil, 1 cup Spanish Onion, 2 teaspoons Garlic
- Add in the diced mushroom stem pieces and sauté until they’ve released their juices. About 6-8 minutes.
- Add in the sauerkraut and corned beef. Stir until combined. Remove from the heat and set aside.
- In a large mixing bowl combine 8 ounces Cream Cheese, 1/2 cup Provolone Cheese (shredded), 1/4 cup Gruyere Cheese (shredded), ¼ cup Thousand Island Dressing, 1 tablespoon Spicy Brown Mustard, and 1.5 teaspoons Dried Chives.8 ounces Cream Cheese, 1/2 cup Provolone Cheese, 1/4 cup Gruyere Cheese, ¼ cup Thousand Island Dressing, 1 tablespoon Spicy Brown Mustard, 1.5 teaspoons Dried Chives
- Then stir in the mushroom, onion, sauerkraut, corned beef mixture.
- Preheat the oven to 350 degrees F. Line the rimmed baking sheet with heavy duty aluminum foil for easy clean up if you wish. Place the wire rack on top of the pan.
- Spoon the filling into the mushroom caps and place on the wire rack. You will be able to mound the filling on top of each mushroom as well. If you have a mushroom that keeps rolling all over the place, use a sharp knife to take a sliver off the bottom, creating a flat surface.
- Bake for 40 - 45 minutes. Serve warm. If you need to hold these until your guests arrive, you can keep them in the oven on Warm (on my oven, this is 180 degrees F) until ready to serve. Garnish with 1/2 cup Green Onions and / or additional dried chives if desired.1/2 cup Green Onions
Equipment
- Grapefruit Spoon or Pointed End of a Peeler for getting everything out of the mushroom caps
- Grater if you can’t find pre-shredded cheese
- Large Mixing Bowl
- Wire Rack Insert for Rimmed Baking Sheet optional, but keeps the mushrooms up out of their juices while baking
Notes
- Corned Beef
- I bought corned beef that was already brined and came with a spice packet. I cooked it sous vide and it came out perfectly. You can find my instructions here [INSERT LINK TO CORNED BEEF PAGE]. After the corned beef is done cooking, let it cool a bit on the counter, remove it from the bag of liquid that was produced by the cooking process, stick it in another zip top bag and stash it in the freezer for 30 minutes before slicing and dicing. This will help it to firm up a bit, making it easier to cut up.
- You could also just buy corned beef from the deli.
- You only need ½ pound of the corned beef for this recipe, so I recommend either using another 1 pound to make my Reuben Raclette Casserole or saving it to slice for sandwiches later in the week.
