Keto Chicken Broccoli Casserole (Low Carb Chicken Divan)

I love making chicken divan casserole because it's cozy, creamy, and packed with flavor. It's one of those comforting family dinners that comes together quickly with just a few simple ingredients.

I grew up eating this classic casserole at my aunt's house, and now it's a family favorite in our own kitchen-with a low carb twist! By making a few simple swaps, this keto chicken casserole delivers all the cozy flavor you love with just 7 net carbs per serving.

You'll love this recipe because it's high in protein, full of vegetables, and perfect for meal prep. The creamy sauce made with mayo, curry powder, and lemon juice gives it a classic flavor that feels like home and there's no condensed soup needed if you prefer homemade.

Things to Know Before Making Chicken Divan Casserole

• Use fresh broccoli: For the best texture, cook it until just crisp-tender so it doesn't get mushy when baked.
• Homemade is best: A homemade cream of chicken soup gives better flavor and keeps the carbs low.
• Grate cheese fresh: Pre-shredded cheese has starch added that can affect texture and carbs.
• Don't skip the lemon juice: It brightens the sauce and balances the richness.

I've been testing and sharing easy casserole and high-protein family dinners since 2018, helping home cooks make simple meals that taste amazing without extra effort.

How to Make Chicken Divan Casserole

Step 1: Preheat the oven to 350°F and grease a 7x11-inch baking dish. Microwave the broccoli in a covered dish for about 4 minutes, until crisp-tender.

Step 2: In a medium bowl, whisk together the cream of chicken soup, mayonnaise, curry powder, lemon juice, salt, and pepper until smooth and creamy.

Step 3: Spread the cooked chicken evenly on the bottom of the baking dish, then layer the broccoli over the top.

Step 4: Use a spatula to gently spread the sauce mixture over the broccoli, then sprinkle with 1 cup of shredded cheddar cheese.

Step 5: Bake for 25-30 minutes, until heated through and bubbling. Serve warm and enjoy your creamy, cheesy chicken divan!

Substitutions and Variations

• Use rotisserie chicken for a shortcut - just reduce the added salt.
• Swap cheddar for Colby Jack or Monterey Jack for a milder flavor.
• To keep the carbs as low as possible, shred the cheese from a block instead of buying pre-shredded cheese (plus, it does taste better!).
• Try Greek yogurt instead of mayo for a lighter option.
• Add a sprinkle of parmesan cheese or breadcrumbs on top for extra texture.

What to Serve with Chicken Divan Casserole

Serve this creamy chicken and broccoli casserole with a side of Cauliflower Rice, Air Fryer Green Beans, or a simple garden salad for a balanced meal. It also pairs beautifully with Keto Garlic Bread for a cozy weeknight dinner.

Refrigerate leftovers in an airtight container for 3-4 days. Reheat in the oven at 350°F until warm, or microwave individual portions for 1-2 minutes. Freeze leftovers for up to 3 months, and thaw overnight in the fridge before reheating.
