Cheesy roasted vegetable and sausage casserole is everything your family craves for dinner. Mix it, bake it, serve up a dish full of hearty deliciousness. Easy to make ahead and cook on a busy night.
Spring cleaning in my house means using up all the random fridge and pantry odds and ends in preparation for an abundance of fresh summer ingredients.
Odds+Ends=Casserole.
I’m somewhat of a casserole aficionado when it comes to cooking freezer meals for pregnant friends, but I don’t often make casseroles for The Hubs and I at home. Partly because I don’t always love all my food mixed together, but mostly because I rarely eat leftovers.
When I was challenged by my 12 blogger friends to make a casserole this month, I decided it was a great way to clear out some crisper drawer space since my CSA vegetables were piling up after being out of town.
Cheesy Roasted Vegetable and Sausage Casserole
We all know The Hubs complains if it’s meatless, so I added some sweet Italian sausage I found in the freezer. This recipe could easily be made with ground beef or turkey, turkey sausage or any kind of sausage your family enjoys.
Don’t feel stuck with the vegetables listed in the recipe either. Substitute any firm, roasting-friendly vegetable like kohlrabi, parsnips, carrots or radishes.
Roasting the vegetables ahead of time allowed them to retain a firmer texture than if they just boiled in the cheese sauce. Plus it gives them that rich flavor you can’t get from a simple boil or blanch.
No gruyere? No problem! Cheddar, Mexican cheese blend, Swiss, mozzarella. Any good melting cheese will taste great in this sausage casserole.
Do you see where I’m going with this? Casseroles are pretty foolproof. Throw together what you have. Vegetables, meats and cheeses and you’re bound to have a crowd pleasing recipe on your hands.
Not too shabby if you ask me. I mean, cheese really does make everything better. 
If you give this recipe a try, I’d love to see it! Tag me @betsylife on Facebook or Instagram and I’ll share your creations!
