How to Make One-Pot Sausage and Potato Casserole Recipe
Step 1 — Prep & Ready
Start by preheating your oven to 375°F (190°C). While it warms up, slice the sausage into bite-sized rounds and halve the baby potatoes to ensure they cook through in perfect time. Dice the onion and mince the garlic so they cook quickly and evenly, adding a cozy aroma as they sauté. Setting everything out beforehand will make this part feel smooth and relaxed.
Step 2 — Cook with Confidence
Heat olive oil in a large oven-safe pot over medium heat. Add the sausage slices and brown them well — about 5 minutes. You’ll notice the edges crisping and the kitchen filling with smoky goodness. Remove the sausage and set it aside (don’t clean the pot; those flavorful bits are gold!). Next, add onion and garlic and sauté until soft and fragrant, just 3 minutes or so.
Then, stir in the halved potatoes, broccoli florets, chicken broth, Italian seasoning, salt, and pepper. Bring the mixture to a gentle simmer — the broth will start to bubble, and your kitchen will smell amazing. Pop the sausage back in, cover the pot with its lid or foil, and transfer to the oven. Bake for 25 to 30 minutes until the potatoes are fork-tender.
Step 3 — Finish & Serve
Once the potatoes are cooked just right, pull the pot out and sprinkle the shredded cheddar cheese evenly over the top. Pop it back in the oven for 5 minutes to melt the cheese into a gooey, luscious layer. Serve this casserole warm and watch it disappear! You’ll love the mix of crispy sausage, soft potatoes, tender broccoli, and creamy cheese in every bite.
Extra Helpful Tips
I’ve learned a few tricks along the way to make this One-Pot Sausage and Potato Casserole Recipe shine every time. Don’t stress if it looks a little liquidy before baking — the potatoes soak up the broth beautifully. And if you prefer a bit more crisp on your sausage, feel free to pop the pot under the broiler for just a minute or two at the end.
- Watch for This Sign: Potatoes are ready when your fork slides in easily but still holds the shape.
- Temperature Trick: Using a moderate oven heat (375°F) keeps everything tender without drying out the sausage.
- Prep-Ahead Option: You can chop the veggies and slice sausage the night before to speed things up.
- Avoid This Common Mistake: Don’t skip browning the sausage; it builds so much flavor!
Serve & Enjoy
Easy Enhancements
Want to jazz up the One-Pot Sausage and Potato Casserole Recipe? Sprinkle some fresh chopped parsley or chives on top for a burst of color and freshness. A drizzle of tangy mustard or a splash of hot sauce brings out the sausage’s savory notes perfectly. For extra indulgence, swirl in a bit of sour cream or creme fraiche just before serving — it adds a silky finish that’s irresistible.
Tasty Pairings
This casserole pairs beautifully with a crisp green salad dressed simply with lemon and olive oil. If you’re craving a crunch, garlic bread or warm crusty rolls work wonders alongside. For drinks, a light beer or a chilled white wine balances the richness, but a sparkling water with a splash of citrus also keeps things fresh and bright.
Quick Plating Tips
When you serve, scoop generous portions straight from the pot to showcase that gooey cheese melting off the edges. Garnish with a little grated cheese or some freshly cracked black pepper on top for a polished look. I find that colorful napkins or rustic plates make this homey casserole feel just a bit more special, even on a busy weeknight.
Store, Freeze & Reheat
Fridge Storage
Leftovers keep well in an airtight container in the fridge for up to 3 days. You may notice the potatoes absorb more liquid and the casserole firms up, but a quick reheat warms things beautifully without losing flavor.
Freezer Friendly?
This recipe freezes nicely if you skip the cheese topping before freezing. Thaw overnight in the fridge and add the cheese before reheating, to avoid sogginess and keep that melty topping fresh and delicious.
Reheat Like New
For reheating, the oven is your best friend—cover loosely with foil and warm at 350°F until heated through. If short on time, microwave on medium power in intervals to keep the sausage juicy and potatoes tender. Adding a splash of broth before reheating helps maintain moisture and prevents dryness.
