Servings: 6


  • 2 lb. lean ground beef
  • 1 medium green bell pepper, diced
  • 1 medium yellow onion, diced
  • 3-4 large Russet potatoes
  • 8 oz. grated sharp cheddar cheese
  • 2 C 1/2 & 1/2 cream
  • 1/2 C Ranch salad dressing
  • 1/4 C grated Colby Jack cheese
  • 1/2 tsp salt
  • 1/2 tsp minced garlic
  • 1/4 tsp ground black pepper
  • extra salt for potatoes
  • parsley for garnish, if desired


  • Preheat oven to 350° Fahrenheit. Lightly grease 9x13 baking dish with olive oil.
  • While oven is heating brown lean ground beef in a large skillet over medium heat. Add diced onion, bell pepper, salt, pepper and garlic while browning. Drain away any excess fat using a colander. Set aside.
  • In a medium sauce pan, warm the 1/2 & 1/2 on low heat. Stir in the Ranch dressing. While constantly stirring, slowly add the grated cheddar cheese. Stir until cheese is completely melted and completely incorporated into the cream. Set aside.
  • Using either a mandolin or a sharp knife, slice the potatoes into 1/2" thick medallions.
  • Line the bottom of the baking dish with potato medallions, allowing them to overlap slightly. Sprinkle with extra salt. Cover with 1/2 of the beef. Pour 1/2 of the cheese sauce on top. Using the back of a spoon, massage the sauce a little to work it down into the beef. Repeat to create a second layer of beef and potatoes.
  • Top with a layer of overlapping potatoes, salt and the Colby Jack cheese. Bake in preheated oven for 50 minutes to an hour until the edges are golden and bubbly.

Do I have to include the green bell peppers if I have family members who don’t like them?

  • Of course not!  This recipe is delicious without the peppers if that is what will make your family happy.  
  • Looking for a bell pepper substitute?  This meat & potatoes casserole is out of this world with canned diced green chiles!  Use 6-8 oz, drained.

Can I make this recipe in the crock pot or prep ahead of time?

  • You sure can!  Look for specific instructions in the post above!

Even though I drained my ground beef after browning, there still seems to be some “grease” that has risen to the top of my casserole.  What happened?

  • Cheese can be “greasy” as it does have dairy fat.  There are a myriad of reasons that this can happen.  See here.  Also, there will be some water that cooks out of your potatoes.  If you have extra “water” or “grease” on the top of your casserole, just dab away with a paper towel before serving.
