It was one of those evenings where I wanted something hearty, satisfying, and unfussy. The kind of dish that fills the kitchen with rich aromas and brings everyone to the table without even needing to call them. I had some sausage in the fridge, a few golden potatoes on the counter, and a hunch that garlic and parmesan could tie it all together.
I tossed everything into a casserole dish — a few extra herbs here, a sprinkle of cheese there — and let the oven do the rest. As it baked, the garlic melted into the potatoes, the sausage crisped up just enough, and that golden crust of parmesan on top? Pure comfort food magic.
This casserole has become a go-to for weeknights and lazy Sundays alike. Simple, savory, and packed with bold flavor, it’s everything you want in a one-dish dinner.

- 3 tbsp olive oil
- 4 garlic cloves, minced
- 1 tsp Italian seasoning
- 1 tsp salt
- ½ tsp black pepper
- ½ cup grated parmesan cheese (plus more for topping)

Cooking Instructions
Step 1: Preheat and prep
Preheat your oven to 400°F (200°C). Lightly grease a 9×13” baking dish.
Step 2: Mix the casserole
In a large bowl, toss together halved potatoes, sliced sausage, olive oil, minced garlic, Italian seasoning, salt, pepper, and ½ cup grated parmesan. Make sure everything is well coated.
Step 3: Bake it
Spread the mixture evenly into the prepared dish. Cover loosely with foil and bake for 30 minutes.
Step 4: Uncover and crisp
Remove the foil, stir the casserole gently, and sprinkle with shredded mozzarella (if using) and a little more parmesan. Bake uncovered for another 15–20 minutes, or until the potatoes are tender and the top is golden.
