Rocky Mountain Casserole–Instant Pot or slow cooker breakfast casserole with hashbrowns, bacon, eggs, green chiles and cheese.

Rocky Mountain Casserole
Today’s recipe is a tasty egg casserole that you can make in your Instant Pot or slow cooker. It’s got eggs, bacon, hashbrowns, cheese, green chiles and cottage cheese. Even if you don’t like cottage cheese you’ll like this casserole! The cottage cheese adds some texture and extra protein and after it’s baked you don’t notice that it is there. I like to make breakfast for dinner every now and then so I served this for dinner. If you have leftovers you can warm them up for breakfast the next morning.
This recipe is adapted from Rocky Mountain Scramble on Amish 365.
Ingredients/Substitution Ideas
- Southern hashbrowns–these are frozen potato cubes with onion and bell pepper.
- Salt and pepper
- Cottage cheese–or ricotta, greek yogurt
- Large eggs–or 6 medium eggs
- Minced dried onion
- Diced green chiles–I used mild
- Bacon crumbles–I buy the big bag at Costco
- Cheddar cheese–I like using sharp
Steps
Spray an oven safe dish that fits inside your Instant Pot with non-stick cooking spray (I used a stainless steel pan*). Place the hashbrowns inside the pan. Sprinkle with a pinch of salt and pepper.

In a bowl whisk together the cottage cheese, eggs, onion, green chiles and bacon.

Pour the mixture over the hashbrowns. Loosely tent the pan with foil.

Pour 1 ½ cups of water into bottom of Instant Pot. Place the pan on a trivet/sling* and lower the pan into the Instant Pot.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 20 minutes. When time is up let pot sit for 5-10 minutes and then move valve to venting. Remove the lid. Remove the pan and foil.

Sprinkle the cheese on top and let it melt (I stuck it under oven’s broiler). Serve and enjoy!

Notes/Tips
- For a full breakfast serve with strawberries, toast and yogurt.
- Try using cooked sausage crumbles or some cubed ham instead of bacon.
- I used my 6 quart Instant Pot*. You can also make this in an 8 quart pot.
- This recipe is gluten-free.
- If you’re using your slow cooker you can double this recipe and keep the same cooking time. Don’t double this recipe in the Instant Pot though. It won’t cook properly.
- I used one of these stainless steel pans* to cook the breakfast casserole using the pot-in-pot method.
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
- Other recipes you can make with bacon crumbles are Anthony’s Chicken and Lori’s Casserole.

I am cooking in crockpot – do the potatoes need to be thawed or and you just put them in cold from the freezer?
they do not need to be thawed
Pretty good. I doubled the recipe and baked it in a 9×13 pan for about 40 minutes at 350 degrees.
Thanks Amber!
Hi there, was wondering if this can be cooked in the oven per chance?
I bet it could! Spray a pan with non stick spray first. Bake at 350 for maybe 25-30 minutes??
Awesome, thanks so much!!
