Butternut Squash Sausage Casserole - detail 1

Ingredients List

  • 1 medium butternut squash, peeled and cubed
  • 1 pound sausage, crumbled (feel free to pick your favorite type!)
  • 1 onion, chopped
  • 2 cloves garlic, minced
  • 1 cup chicken broth
  • 1 teaspoon thyme
  • 1 teaspoon rosemary
  • Salt and pepper to taste

How to Prepare the Butternut Squash Sausage Casserole

Preheat the Oven

First things first, let’s get that oven preheating! Set it to 375°F (190°C) so it’s nice and warm by the time we’re ready to pop our casserole in. A hot oven is key for getting that perfect texture.

Cook the Sausage

Now, grab a large skillet and cook your crumbled sausage over medium heat. You want it to get beautifully browned and release all those savory juices—this is where the flavor really starts! It should take about 5-7 minutes, but keep an eye on it and stir occasionally so it cooks evenly.

Sauté Onion and Garlic

Once your sausage is looking delicious, add in the chopped onion and minced garlic. Sauté these together until the onion is softened and translucent, about 3-4 minutes. Oh, the aroma is heavenly—trust me, you’re going to love this part!

Combine Ingredients

Now it’s time to bring in the star of the show! Add the cubed butternut squash, chicken broth, thyme, rosemary, salt, and pepper to the skillet. Give it a good stir to combine everything. Bring this mixture to a gentle simmer and let it cook for about 10 minutes. This step allows the squash to soak up all those wonderful flavors while getting just tender enough for baking.

Transfer and Bake

Once you’ve simmered it, transfer everything to a casserole dish. Spread it out evenly so it bakes nicely. Now, pop it in the oven and let it bake for 25-30 minutes. You’ll know it’s done when the squash is tender and the edges are bubbling—absolutely mouthwatering! Keep an eye on it towards the end to avoid overcooking. And just like that, your Butternut Squash Sausage Casserole is ready to shine!

Tips for Success

To really nail this Butternut Squash Sausage Casserole, I’ve got some handy tips that will elevate your dish to the next level!

  • Choose the Right Sausage: Don’t hesitate to experiment with different types of sausage! Sweet Italian, spicy chorizo, or even a turkey sausage can change the whole flavor profile. Trust your taste buds!
  • Cut Your Squash Evenly: Make sure to cube your butternut squash into similar sizes for even cooking. This way, every bite will be perfectly tender.
  • Season Generously: Don’t be shy with the salt and pepper! A little extra seasoning can make all the difference, so taste as you go.
  • Cheesy Goodness: If you love cheese (who doesn’t?), sprinkle some shredded cheese on top in the last 5 minutes of baking for a melty, golden finish!
  • Make Ahead: This casserole stores well, so feel free to make it a day in advance. Just reheat in the oven until warmed through—easy peasy!

Now you’re armed with the tips to make this casserole a hit! Enjoy the cooking process and the delicious results that follow!

  • Fresh Green Salad: A crisp, refreshing salad tossed with a light vinaigrette is the perfect complement to the hearty casserole. Try a mix of arugula, spinach, and sliced apples for a sweet and peppery contrast!

These sides not only complement the flavors but also make for a well-rounded, satisfying meal. Enjoy experimenting with different combinations to find your perfect match!

Storage & Reheating Instructions

Got leftovers? Don’t worry, my Butternut Squash Sausage Casserole stores beautifully! To keep it fresh, let the casserole cool completely before storing. Then, transfer it to an airtight container or cover the dish tightly with plastic wrap or aluminum foil. It’ll stay good in the refrigerator for up to 3-4 days—perfect for those busy nights when you want a quick meal!

If you want to keep it longer, you can freeze it! Just make sure to portion it into smaller containers for easy reheating later. It can be frozen for up to 2 months. To thaw, simply move it to the fridge the night before you plan to enjoy it again.

When it’s time to reheat, you have a couple of options. For the best results, pop it back in the oven at 350°F (175°C) until warmed through, which usually takes about 20-25 minutes. If you’re in a hurry, you can use the microwave—just cover the container to avoid splattering and heat in short intervals, stirring in between until hot. I recommend adding a splash of chicken broth if it seems a bit dry after reheating! Enjoy your delicious casserole all over again!
