Keto Cheesy Broccoli Chicken

I stumbled onto this recipe on a Tuesday night when my fridge was looking sparse and my keto streak was wavering. A rotisserie chicken, some broccoli, and whatever cheese I had on hand seemed like the obvious solution, but I had no idea how transformative those few simple ingredients could be when baked together. That first bite—creamy, cheesy, deeply satisfying—made me realize I'd accidentally created something that would become a weekly staple. Now I make it when I need comfort without the guilt, and honestly, it's become the dish I reach for when feeding people who are skeptical about low-carb cooking.

I remember serving this at a casual dinner party where one guest mentioned she was trying keto but got tired of the same meals over and over. When I brought this bubbly, golden-topped casserole to the table, her expression shifted—suddenly it didn't feel restrictive anymore, just genuinely delicious. She texted me the recipe request before dessert, and that moment cemented for me that this dish has a quiet power to make people feel included rather than left out.

Ingredients

• Chicken breasts (2 large, about 500 g): Cooked and shredded or cubed, they're the protein backbone here; I've found that slightly underseasoning them works better because the sauce adds plenty of flavor.
• Fresh broccoli florets (400 g, about 4 cups): Cut into bite-sized pieces so they cook evenly and stay tender without turning mushy, which happens faster than you'd think.
• Garlic (2 cloves): Minced and sautéed briefly, it wakes up the whole dish with one of those smells that tells you something good is happening.
• Shredded cheddar cheese (200 g, 2 cups): Use the kind you shred yourself if you have time—pre-shredded cheese has anti-caking agents that sometimes make the sauce feel grainy.
• Cream cheese (60 g, 1/4 cup): Softened at room temperature, it creates that luxurious, creamy base without needing flour or thickeners.
• Heavy cream (120 ml, 1/2 cup): This is what makes it feel restaurant-quality; don't be tempted to skip it or use milk instead.
• Olive oil (1 tbsp): Just enough to prevent the garlic from sticking, nothing more needed.
• Salt (1/2 tsp) and black pepper (1/4 tsp): Taste as you go because cheese brings its own salt, and oversalting is the one mistake I've made repeatedly.
• Smoked paprika (1/2 tsp): Adds a subtle depth that makes people ask what your secret ingredient is.
• Dried Italian herbs (1/2 tsp): A gentle herb blend that doesn't overpower but keeps the whole thing tasting intentional.

Instructions

Heat your oven and prep your stage:

Set the oven to 200°C (400°F) and lightly grease a medium baking dish—this is when the kitchen starts to feel purposeful. A little oil or butter on the dish prevents sticking and makes cleanup infinitely easier later.

Blanch the broccoli gently:

Steam or microwave the florets for just 2 to 3 minutes until they're tender but still bright green; undercooked is better than overcooked because they'll soften more in the oven. Drain them well afterward so excess water doesn't dilute your sauce.

Wake up the garlic:

Heat olive oil in a skillet over medium heat and add your minced garlic, letting it sizzle for about a minute until the smell becomes almost intoxicating. That aromatic moment tells you you've done it right.

Build the creamy sauce:

In a large bowl, combine the cooked chicken, steamed broccoli, sautéed garlic, half the shredded cheddar, softened cream cheese, heavy cream, salt, pepper, paprika, and Italian herbs. Stir everything together until it's evenly coated and feels almost luxurious—this is where the magic really happens, and you'll notice how the cream cheese melts into everything.

Transfer and crown with cheese:

Pour the entire mixture into your prepared baking dish and spread it into an even layer. Sprinkle the remaining cheddar cheese over the top in an even blanket—this creates that golden, bubbly crown everyone craves.

Bake until golden:

Slide it into the preheated oven for 20 to 25 minutes, watching as the cheese on top transforms into a bubbling, slightly browned masterpiece. You'll know it's done when the edges are gently bubbling and the top cheese has turned golden.

Rest and serve:

Pull it from the oven and let it sit for 5 minutes—this pause lets everything settle and makes serving cleaner. The aroma at this point is almost overwhelming in the best way possible.

There's a moment after the oven door closes when the kitchen fills with this warm, savory aroma that makes you feel like you've done something kind for yourself. That's when I usually pour a cup of tea and sit with the quiet knowledge that dinner is actually handled, and it's going to be something I genuinely want to eat.

Why This Works on Keto

This casserole hits that sweet spot where every single ingredient serves the keto goal without any pretense or compromise. The heavy cream and cheddar provide the fat your body needs, the chicken gives you serious protein, and the broccoli brings fiber plus enough volume to make the dish feel hearty. You're not eating a tiny bowl of sadness—you're eating a full, satisfying dinner that happens to have 7 grams of carbs per serving, which most keto plans can easily absorb.

The Magic of Cream Cheese

I didn't understand why cream cheese mattered until I made this without it once, replacing it with extra heavy cream. The result was technically correct but somehow thin, less luxurious, like the soul had been removed. Cream cheese adds a subtle tang and thickness that regular cream can't achieve—it creates a sauce that clings to the broccoli and chicken rather than pooling at the bottom of the dish.

Flexibility and Variations

This recipe is more forgiving than it appears, which is part of why I reach for it when I'm tired or short on ideas. The base formula—protein, vegetable, creamy sauce, cheese—stays constant while everything else can shift based on what's actually in your kitchen or your mood that day.

• Add Parmesan: Grate 2 tablespoons over the top before baking for extra umami and a sharper cheese flavor.
• Swap the vegetable: Cauliflower works beautifully, or use half broccoli and half cauliflower if you want variety.
• Increase the heat: A pinch of red pepper flakes stirred into the sauce creates a gentle warmth that doesn't overpower the creaminess.

Pin it

This dish has become my quiet proof that keto cooking doesn't mean deprivation—it means choosing ingredients intentionally and letting their natural qualities shine. Make this once, and I think you'll understand why it's earned a permanent spot in my weeknight rotation.
