Prepare the Chicken & Steak:
Heat butter and olive oil in a skillet over medium heat.
Season the cubed chicken and steak with salt and pepper.
Sear the meat in the skillet for about 3-4 minutes, just until browned (don’t cook fully).
Transfer the seared chicken and steak to the crockpot.
Make the Parmesan Cream Sauce:
In the same skillet, add heavy cream, Parmesan cheese, garlic powder, onion powder, and Italian seasoning.
Let the sauce simmer for 5 minutes until it thickens slightly.
Pour the sauce over the chicken and steak in the crockpot.
Crockpot Cooking:
Cover and cook on low for 4 hours (or high for 2 hours).
If desired, add mushrooms or onions halfway through cooking for added flavor.
Prepare the Cheesy Roasted Potatoes:
Preheat the oven to 400°F (200°C).
Toss the cubed potatoes with olive oil, garlic powder, parsley, salt, and pepper.
Roast the potatoes on a baking sheet for 25-30 minutes or until golden and crispy.
Sprinkle with shredded cheddar and grated Parmesan cheese, then return to the oven for another 5 minutes until the cheese melts.
Assemble:
Once the crockpot dish is done, serve the chicken and steak topped with the thickened Parmesan cream sauce.
Garnish with fresh parsley and serve alongside the cheesy roasted potatoes.
