Get out and measure your ingredients.
Preheat your oven to 350 degrees.
Place your skillet over medium to medium-high heat and add your oil until it shimmers or a drop of water flicks and dances.
Add onions and cook until softened. Then add your peppers.
At your work station, place your shredded potatoes in a large bowl.
Combine the potatoes, cheeses, taco seasoning, heavy cream, sour cream, and beef or protein, if using. Combine until blended together.
Prepare a casserole dish with cooking spray and pour mixture into it. Smooth top out into an even, flat layer.
Top with remaining cheese and feel free to add more! Bake for 30-35 minutes or golden, bubbly and heated through.
Remove from oven and serve with salsa, green onions and maybe a fried egg or two! What a way to start the day! ?
Enjoy every bite!
