Instructions
Preheat your oven to 375°F (190°C).

Grease a 9x13-inch casserole dish with cooking spray and set aside.

In a mixing bowl, add the Bisquick, milk, egg, and half of the black pepper.

Combine until the batter is smooth.

Pour the Bisquick mixture into the prepared baking dish.

In a large skillet over medium-high heat, brown the ground beef, about 5-7 minutes.

Add the onion slices and green bell pepper slices to the skillet with the beef and cook until softened, about 5-7 minutes. Drain any excess grease.

Stir the brown gravy mix, water, and the remaining black pepper into the ground beef mixture. Simmer for about 3-5 minutes until the liquid is reduced.

Spread the beef mixture over the Bisquick.

Top with the cheese slices, spacing evenly and tearing the slices as needed for full coverage.

Bake the casserole in the preheated oven for 25-30 minutes, or until the layer of provolone cheese is golden brown and a toothpick inserted in the biscuit layer comes out clean.
Tip: If the cheese becomes too brown before the biscuit layer is done cooking, cover the top of the casserole in aluminum foil.

Allow the casserole to cool for about 10 minutes before slicing and serving.

It was a very easy recipe to put together. I omitted salt and pepper and maybe that was what I felt it was lacking. Don't get me wrong it is good but I felt like it was lacking a tiny bit. Maybe next time I will include an all purpose seasoning to enhance the flavor.

I saw this and had to have it. I did mine with Steak Umms and I used red and green peppers. It came out beautiful and I served it with french cut green beans, corn on the cob and yeast rolls. That was a delicious dinner. Thank you for the recipe and you have a wonderful day.
