30 Healthy Casseroles That Will Keep You on Track

A strata is a baked dish of eggs, bread and cheese. You'll know it's done when the creamy custard turns golden in the oven. Have it for breakfast, lunch or dinner. We won't judge.

Why should regular pasta have all the fun? Cauliflower florets join noodles in this veggie-packed dish, bringing you both nutrition and ooey-gooey cheese in every bite. Sounds like the best of both worlds to us.

This pretty side is gluten-free and vegetarian. Plus, you'll get to make your own potato noodles. Any excuse to use the spiralizer. (But if you don't have one, a cheese grater works fine.)

There's no reason to wait until Thanksgiving to dig into this classic dish. Especially with healthy additions like homemade mushroom Alfredo sauce in place of cream of mushroom soup and fresh baby bella mushrooms.

An old-school dinner that's come a long, long way. This one substitutes brown rice for white and a lean cashew cream sauce for milk and cheese.

A hearty meal to warm you up after a blustery day. Think caramelized cremini mushrooms, lots of fresh thyme, heavy cream and Gruyère.

Your favorite sushi joint is getting jealous. Two cans of tuna get totally transformed with the help of spicy yogurt, nori sheets, grated cucumber and soy sauce. Bonus points for using brown rice instead of white.

Bye, noodles. Instead, we use thin-sliced zucchini and roll it up with garlicky ricotta and mozzarella before pouring on the marinara.

Chicken breast can get old fast. Bring on the fluffy quinoa, broccoli florets and shredded Gruyère. We won't tell if you throw in some bacon either.

With a dinner like this, who needs bread or pasta? (Just kidding. We do.) But this low-carb delight also has a lot to be excited about, like lots of ground turkey and grated mozzarella.

Cheese, beef, sour cream, all the guac...tacos are our kryptonite. Don't worry about breaking your diet on this lean take though; it uses ground chicken or turkey instead of beef, lots of veggies, black beans and quinoa.

We know, we know. This even sounds healthy. And it is. But it's so not a bad thing. Think roasted butternut squash, sweet potato and cauliflower golden and caramelized in a decadent cashew cream. Not to mention the toasted pine-nut topping.

Even your kids will be psyched about this one. It's got all the flavor of takeout plus lots of crispy edamame and brown rice. You can thank honey and brown sugar for the sweet-and-savory sauce.

Nothing screams summer like lemony, buttery seafood. And since shrimp is super lean and healthy, you can have lots of it. Go ahead and make that second plate.

She's paleo. She's Whole30. She's downright delicious. We had no idea tuna casserole could be pretty, but spiralized zucchini, diced green chiles and fresh lemon make it happen.

These enchiladas have a secret: They're totally tortilla-free. Zucchini slices make it low-carb, and the shredded rotisserie chicken is a genius timesaver.

Lasagna doesn't have to mean lots of calories, fat and carbs. Enter this healthy looker, rich with ribbons of butternut squash, garlicky spinach and part-skim mozzarella.

Chicken breast? Again? Boooring. Liven them up with a simple homemade tomato sauce, lots of garlic spinach and fresh mozzarella.

The sweet-potato sauce with garlic, ancho chili powder and cumin? Whoa. It comes together in less than an hour to boot.

One serving of this beauty will only put you back 280 calories. That means you have plenty of wiggle room for a glass of wine. Or two.

This is one meal that's sure to fill you up. We're talking 10 grams of protein per plate. And fair warning, you'll want to put that vegan basil-pesto on everything.

Didn't think this was within your diet's parameters, did you? Almond milk plays the role of heavy cream in this veggie-rich dish.

Give your casserole dish a break and lean on your trusty loaf pan for this one. Tell your trainer there are three cups of veggies (zucchini! bell pepper! peas! corn! yams!) in every meatloaf.

We're picturing you in the yard munching on this with a side salad and a glass of Chardonnay. The gluten-free breadcrumbs, made with seasoned almond meal, won't disappoint.

Ever had celeriac before? This celery root makes for a great noodle substitute. Treat yourself to full-fat coconut milk for the base; it works wonders in the creaminess department.

Pasta who? Pine nuts and lots of fresh sage put this dinner over the top. That means you can impress everyone from your kids to your book club in just under an hour.

It's time to get creative with your lasagna. Skip the noodle sheets and sub zucchini-carrot pancakes instead. Use any cheese your heart desires, from cheddar to ricotta to soy.

Dinner in 40? No problem. Plump cherry tomatoes, sour cream, sliced zucchini and seasoned spinach make tonight's meal a total breeze.

Your favorite takeout spot will miss you. This healthier alternative boasts Szechaun veggies and bean sprouts atop cauliflower or broccoli rice. Add a few runny sunny-side-up eggs for a decadent finisher.

This is the lighter cousin of Thai pad kee mao. Enter fresh zucchini noodles, ground ginger, stir-fry vegetables and a killer sauce made with fish sauce, chili garlic, tamari and red pepper.
