If you’re eating low-carb and want actual warmth on a cold night—not a salad, not another piece of plain grilled chicken—this list is for you. These 13 healthy keto casseroles for cold weather cover everything from fast weeknight protein to slow weekend braises, and most of them feed a crowd without asking much from you technically.
We started with 14 candidates and narrowed it down to recipes that had clear instructions, real photos, and everyday ingredients. What’s left is a deliberately mixed list: a few quick wins for Tuesday nights, a couple of longer projects worth saving for the weekend.
The Ground Beef & Broccoli Casserole from Savory Tooth is the kind of thing you’ll make twice in one week once you see how fast it comes together. On the other end, the Magic Greek Zucchini Casserole takes two and a half hours—but it yields 12 portions and the slow braise is genuinely worth the time when you’ve got it.
Here’s a quick look at all 13 recipes so you can compare cook times and find what fits your night before you click through.

1. Ground Beef & Broccoli Casserole

2. Keto Chicken Tetrazzini
Two creamy soups, sour cream, and Palmini noodles create a casserole that feeds eight in under an hour. The bone broth keeps it light while the butter and cream do the heavy lifting on flavor.

5. Magic Greek Zucchini Casserole
★ Nell's pick: The Magic Greek Zucchini Casserole’s two-and-a-half-hour braise builds complex flavor through slow cooking with cinnamon, ginger, and Greek seasoning, and yields twelve servings that make it the most practical recipe for both feeding a crowd and building a freezer supply through cold months.
This Greek-spiced casserole takes two and a half hours because the slow braise is the point—cinnamon and ginger with lamb or beef create something warm and deeply savory. It yields 12 portions, perfect for a dinner party or freezer-stocking day.
Heads up: Plan ahead: this casserole requires 150 minutes from start to finish.

9. Creamy Garlic Parmesan Mushroom Chicken
Chicken breasts swimming in a garlic parmesan cream sauce with mushrooms reaches the table in under 30 minutes, though it’s technically a pan dish rather than a casserole. The herb-forward seasoning and fresh minced garlic make it feel restaurant-quality.

Picking Your Night
For nights when you’re home late and patience is short, go straight to the sub-30-minute options. The Garlic Butter Salmon and Asparagus is done in 17 minutes, the Keto Beef Stroganoff Casserole in 22, and the Low Carb Cheesy Cabbage Casserole in 28. These are your Tuesday recipes—fast, filling, and not fussy.
If you’re cooking on a Sunday with the oven free, the longer recipes pay off. The Magic Greek Zucchini Casserole takes two and a half hours but makes 12 servings, so you’re really cooking once for several meals. The Keto Chicken Tetrazzini (55 minutes, eight servings) and the Ground Beef & Broccoli Casserole (also 55 minutes) are both strong meal-prep anchors—cook them Sunday, eat them Wednesday.
A few recipes here aren’t strict casseroles—the frittata, the stroganoff, and the garlic parmesan mushroom chicken all lean toward skillet or baked-egg territory—but they fit the same cold-weather, low-carb brief and are worth including for variety. The Keto Spinach Artichoke Dip and the Roasted Brussels Sprouts and Bacon are better used as sides or starters alongside the heartier mains than as standalone dinners.
What to Serve Alongside
Several of these recipes already have built-in vegetables—broccoli in the ground beef casserole, asparagus with the salmon, cabbage in the cheesy cabbage casserole—so you don’t always need a separate side. But for the protein-forward ones like the Keto Beef Stroganoff Casserole or the Creamy Garlic Parmesan Mushroom Chicken, the Roasted Brussels Sprouts and Bacon from Nom Nom Paleo pairs naturally: the aged balsamic cuts through the richness, and it roasts largely hands-off while your main is finishing up.
