Spicy Sausage and Butternut Casserole

Note: this recipe brought to you by my friends at Johnsonville® Sausage!  Of course, all recipes and thoughts are my own.

Butternut squash makes for an amazing Holiday side dish, and cooking it on the grill with a spicy sausage makes an irresistible combination.  The recipe for Grilled Butternut and Sausage Casserole combines Hot Italian Sausage with butternut squash, onions, sage, and maple syrup.  Cooking it on the grill adds that little bit of extra flavor that will leave your normal casseroles in the smoke.

What you need for the Sausage and Butternut Casserole

I cook this recipe entirely on my grill in one pan!  For this recipe, I use a 10″ enameled cast iron skillet.  Three links of fresh Johnsonville Hot Italian Sausage and one pound of cubed butternut squash fit perfectly, and will feed 6-8 people as a hearty side dish.  I also used onions, peppers, spinach, maple syrup, and sage.  For the topping, it was parmesan, panko bread crumbs, and melted butter.  This dish is simple, but the interaction of flavors is fantastic.

Fresh vs Frozen Butternut Squash

In this recipe, I used fresh, cubed, butternut squash.  Now, I didn’t peel it, because that’s a pain.  Luckily, the grocer has nice, fresh, cubed butternut.  If you get frozen butternut cubes, that will work just fine as well, but your cooking time will be shorter.  Frozen vegetables are much better quality than they used to be, but the freezing process does quicken the cooking time.

Putting the Sausage and Butternut Casserole Together

This is a really simple recipe.  I used Johnsonville Hot Italian Sausage links.  They come in a pack of five, but I just used three for this dish.  Start by removing the casings, then brown the sausage while breaking it up (I used the side burner on my grill.) Add in onions, peppers, seasonings, squash, spinach and maple syrup, let that cook a bit, then put in your preheated grill.  I covered the dish with foil after 15 minutes to help the fresh squash steam tender, then removed the cover and added the topping.  That’s it- so easy!
