How to Make Easy Keto Philly Cheesesteak Stuffed Peppers
Letโs dive into the fun partโmaking these Easy Keto Philly Cheesesteak Stuffed Peppers! Follow these simple steps for a dish thatโs bound to impress.
Step 1: Preheat the Oven
Preheat your oven to 400ยฐF (200ยฐC) so itโs nice and toasty for our peppers!
Step 2: Prep the Peppers
In a 13ร9โ baking dish, place the halved green bell peppers with the open side facing up. Set them aside as we prepare the filling.
Step 3: Season the Steak
Generously season both sides of the top sirloin steak with salt and pepper, ensuring every bite is bursting with flavor.
Step 4: Sear the Steak
Heat a large skillet over high heat and spray it with cooking spray. Sear the seasoned steak for about 2-3 minutes on each side until itโs beautifully browned.
Step 5: Sautรฉ the Veggies
Once the steak is rested, spray the pan again and toss in the sliced mushrooms. Sautรฉ until theyโre golden brown, about 3-4 minutes. Then add in the red pepper and onion, sautรฉing for another 2-3 minutes until the onions become translucent and the veggies are tender.
Step 6: Combine Ingredients
Transfer the sautรฉed veggies into a large bowl. Thinly slice the rested steak and add it to the bowl with the veggies. Now, add the mayonnaise, Dijon mustard, garlic powder, ground black pepper, and mozzarella cheese. Stir well to combine all those delicious flavors!
Step 7: Stuff the Peppers
Generously fill each halved green bell pepper with the scrumptious steak mixture, packing it in for maximum flavor.
Step 8: Bake to Perfection
Pop the stuffed peppers into your preheated oven and bake for 30 minutes. Youโll know theyโre ready when theyโre tender and the cheese is bubbly!
Step 9: Garnish and Serve
Sprinkle with chopped parsley for a fresh finish, and voila! Your Easy Keto Philly Cheesesteak Stuffed Peppers are ready to impress!
