- ½ cup water – For steaming the sausages to lock in moisture.

How to Make This Keto Italian Sausage Casserole
Ready to get cooking? Follow these simple steps:
Step 1: Sear the Sausages
Start by browning your sausages in a skillet over medium heat. This step is crucial—it adds depth and richness to the dish. Once both sides are golden brown, add ½ cup of water, cover the skillet, and let them simmer for about 8-12 minutes. This ensures they stay juicy and tender.
Step 2: Assemble the Casserole
Transfer the seared sausages to a greased casserole dish. Pour the marinara sauce evenly over the top, making sure each sausage is coated. Sprinkle the mozzarella and Parmesan cheeses generously, then finish with a dash of Italian seasoning, garlic powder, basil, and black pepper.
Step 3: Bake to Perfection
Pop the dish into the oven and bake for 18 minutes. For extra bubbly cheese, move it to the top rack for the last 2 minutes—or broil it for 1 minute if you’re feeling bold. Keep an eye on it, though, because nobody likes burnt cheese!
