10 Low-Carb Casseroles That Are Loaded with Fresh Veggies

Casseroles are a weeknight staple for many families — and for good reason. They’re often very simple to make, filling enough to feed a group, and they have the built-in, one-pan ease that’s required for busy weeknights. Casseroles can also be customized to fit any and all cravings or dietary preferences. And now that we’re more than halfway through summer? We’re reaching for balanced, satisfying versions that make excellent use of seasonal produce.-
Below you’ll find several of our favorite casserole recipes — all of which are low carb and vegetable-forward. The majority feature everything we love about casseroles: easy prep, even easier cleanup, and leftovers that taste just as good (if not better!) the next day.

This colorful bake is loaded with plenty of produce — spinach, red peppers, carrots — but you can swap in almost any chopped veggies you might have on hand. To keep it low-carb, just leave out the diced potatoes.

This keto-friendly dinner — with chicken breasts, artichokes, and fresh tomatoes — only needs 10 minutes of quick prep before it bakes in the oven. Plus, cleanup is a total breeze.

You’ll cook a few bacon strips in a skillet, then brown Brussels sprouts right in the renderings before finishing everything in the oven. The key secret ingredient here? A bit of tangy Dijon mustard spooned into the mixture just before it bakes.

Serve this low-carb casserole as a side to your protein of choice — or enjoy it as a vegetarian main. This also reheats well as a lunch option, and leftovers will keep for several days.

This takes its inspiration from decadent loaded potato casseroles — but puts a low-carb spin on things by swapping in cauliflower florets as the base. Don’t forget the crispy bacon on top!

Creamy, cheesy spaghetti squash is satisfying on its own — but you could also mix in your favorite protein to round things out, like leftover rotisserie chicken, ground turkey or beef, or tuna.

This is a no-fail side that everyone will love — and it bakes up in just about 20 minutes. Toss it under the broiler at the end for extra color and crisp, then pair it with your favorite protein for a full meal.

Consider this your latest reminder that eggs should definitely not be limited to just breakfast. This veggie-forward casserole — loaded with asparagus, broccoli, and cherry tomatoes — is hearty enough for lunch or dinner.

Fair warning that this recipe requires a decent amount of prep — most of which goes to making the homemade mushroom Bolognese sauce. (But it’s worth it, and you’ll want to spoon it over just about everything.)

Even if you’re not the biggest fan of cauliflower, you’d be hard-pressed not to like it here, where it’s paired with a trio of crowd-pleasers: chicken, bacon, and cheese. (Plus broccoli, of course!)
