Roasted Broccoli, Cauliflower, & Chicken Sausage Casserole

Low carb comfort food deliciousness? Gluten free goodness? Keto friendly happiness? Oh yes, it’s all that and more: This Roasted Broccoli, Cauliflower, & Chicken Sausage Casserole packs in all of the filling flavor you need — but less of what you may not want!

Who’s hungry for some cheesy comfort food today? This Roasted Broccoli, Cauliflower, & Chicken Sausage Casserole might just do the trick. Try it on a Sunday evening when you have time to devote to roasting the veggies. Because of that pre-roasting step, today’s recipe takes a little more time than you might have available on a busy weeknight — but, this is also what locks in all the flavor!

I’ve been a long-time fan of ALDI’s pre-cooked Never Any chicken sausage (see this earlier chicken sausage recipe roundup for more ideas on how to use it). Here, the slight sweetness of their chicken apple sausage provides just the right counterpoint to spiced-up cheesy vegetables in today’s comfort food casserole.

Yes, this casserole contains exactly what it looks like: A cheesy mess of oven roasted vegetables, baked up together with some browned chicken sausage and onion. Pretty? Well, beauty sometimes lies in the eye of the beholder, right? (Or… the be-eater!) While cheesy roasted cauliflower & chicken sausage may not be visually pretty, it’s pretty darn delicious.

College Guy was a particularly big fan, and easily dispatched of the leftovers for lunch the next day. (This casserole does reheat quite nicely, making it great for leftover lunches or to make and portion out for meal prep.)

We're making our own version of this recipe again, and it's becoming a family favorite. Today we replaced the cauliflower with potatoes, because that's what we need to use up. My family likes this better with kielbasa or bratwurst, rather than chicken sausage. Thank you for this great, adaptable, recipe!
