Ingredients

• For the Low-Carb Meatballs
• 1 lb / 450g Lean Ground Beef
• 1 large Egg
• ¼ cup / 30g Low-Carb Breading & Crusting Mix (or crushed pork rinds)
• 1 tsp / 6g Salt
• 1 tsp Dried Oregano
• 1 tbsp / 4g Fresh Parsley, chopped
• ½ tsp Garlic Powder
• ½ tsp Ground Black Pepper
• For the Savory Broth
• 2 cups / 480ml Beef Broth
• ½ medium Green Bell Pepper, diced
• ½ medium Red Bell Pepper, diced
• 1 stalk Celery, diced
• ½ cup / 75g Red Onion, diced
• 5 large Mushrooms, diced
• For the Velvety Cheese Sauce
• 4 tbsp / 60ml Water
• 4 tbsp / 60ml Heavy Cream
• 4 tbsp / 57g Butter
• 8 slices American Cheese

Instructions

1. Step-by-Step
2. In a large mixing bowl, combine the ground beef, egg, low-carb breading mix, salt, oregano, chopped parsley, garlic powder, and black pepper. Use your hands to gently mix until all are just combined—be careful not to overwork the meat.
3. Roll the mixture into 12 evenly-sized meatballs, about 2 inches in diameter. Set them aside.
4. Pour the beef broth into the inner pot of your Instant Pot. Add the diced green and red bell peppers, celery, red onion, and mushrooms. Give it a quick stir.
5. Gently place the meatballs into the broth, arranging them in a single layer as much as possible.
6. Secure and lock the Instant Pot lid. Set the steam release valve to the ‘Sealing’ position. Select the ‘Manual’ or ‘Pressure Cook’ setting and cook on high pressure for 10 minutes.
7. While the meatballs are cooking, prepare the cheese sauce. In a microwave-safe bowl, combine the water, heavy cream, butter, and American cheese slices.
8. Microwave the sauce for 2-3 minutes, stopping to stir every 30 seconds, until the cheese is fully melted and the sauce is smooth and blended.
9. Once the 10-minute cooking time is up, carefully perform a quick release of the pressure. Once the pin drops, unlock and remove the lid.
10. Pour the warm cheese sauce over the meatballs and vegetables in the pot. Gently stir to coat everything in the creamy sauce. Serve immediately and enjoy!
