Ingredients
- Your favorite sausage sliced: The sausage brings savory richness Try to use one with snappy casing and plenty of flavor Pork chicken or plant based all work
- Medium sized potatoes peeled and chopped: Potatoes add comforting starch Choose firm potatoes like Yukon Golds or Russets for best texture
- Asparagus trimmed and cut: Fresh asparagus gives the dish a vibrant spring touch Look for spears that are firm and deep green
- Yellow onion diced: Onion brings subtle sweetness A fresh onion is best for depth
- Garlic minced: A couple of cloves add aromatic punch Use fresh garlic for boldest flavor
- Shredded cheddar cheese: Melts creamy and golden all over the casserole Go for sharp cheddar and grate it yourself for best melt and taste
- Chicken or vegetable broth: Moistens everything and helps flavors meld Pick a good quality broth with real ingredients
- Olive oil: Needed for sautéing and adds subtle flavor Use extra virgin for best taste
- Dried thyme: Contributes herby warmth Check your thyme is fragrant and not outdated
- Salt and pepper: Brings the flavors together Always taste before baking and season as needed
- Fresh parsley for garnish: Adds a pop of green and freshness Pick bright flat leaf for best look and taste
Step-by-Step Instructions
- Prep the Oven and Dish:
- Preheat your oven to 375°F or 190°C This ensures the casserole bakes evenly and gets golden on top Lightly grease a 9x13 inch baking dish with a little olive oil to keep things from sticking
- Brown the Sausage:
- In a large skillet over medium heat cook your sliced sausage until its edges get crisp and caramelized This step draws out flavor and makes every bite hearty Set aside on a plate to catch any juices
- Cook the Potatoes:
- Using the same skillet add all your chopped potatoes Give them around 10 minutes stirring now and then until the outsides are turning golden and they are just starting to soften If the pan looks dry drizzle in a bit more oil
- Add Onion and Garlic:
- Toss in the diced onion plus the minced garlic Stir and cook for three to five more minutes The onion should turn translucent and fragrant cooking low and slow so nothing burns
- Combine in the Baking Dish:
- Transfer the potatoes onion garlic and browned sausage to your prepared baking dish Gently fold in the chopped asparagus to mix everything evenly This layering gives you variety in each bite
- Add Broth and Seasonings:
- Pour the broth gently over everything letting it seep into the corners Then scatter thyme salt and pepper on top so each bite gets a share of seasoning
- Bake Covered:
- Cover the casserole snugly with foil Place it in the oven for 20 minutes This step steams the potatoes and melds the flavors without drying them out
- Add Cheese and Finish Baking:
- Carefully remove the foil Sprinkle cheddar cheese evenly across the surface Return the dish to the oven uncovered Bake for another 15 minutes The cheese should melt and bubble into a beautiful golden topping
- Serve and Garnish:
- Let the casserole rest for a few minutes so flavors settle Scatter chopped parsley on top for a fresh finish then serve warm scooping down to get a bit of everything in each serving

Cheddar is my favorite part here I love how it crisps around the edges and makes the whole kitchen smell amazing My son always grabs the cheesiest piece first and it is now a standing joke in our family that you have to be quick with the spatula
