Keto Cheesy Broccoli Chicken

One Tuesday evening, I stood in front of my pantry feeling that familiar keto fatigue—the one where you've eaten the same things for weeks and suddenly chicken and broccoli feels impossible. But then I remembered an old trick from my mom's kitchen: throw everything creamy and cheesy into a baking dish and let the oven do the work. That night, this casserole was born, and it became the answer to my 6 PM panic that keeps happening.

My partner walked into the kitchen as it came out of the oven, and the smell stopped him mid-sentence. We sat down and ate it straight from the dish with no sides, no fanfare, just two people realizing this humble casserole had actually solved something. He asked when I was making it again before he'd even finished his first bite.

Ingredients

• Cooked chicken breasts (2 large, about 500 g): Whether you roast them yourself or grab a rotisserie bird from the store, the quality of this protein sets the tone for everything else—shredding versus cubing is purely your texture preference.
• Fresh broccoli florets (400 g, about 4 cups): Cut them smaller than you think you should; they'll soften slightly in the oven and you want them to feel integrated, not like vegetables you're tolerating.
• Garlic (2 cloves, minced): This small amount builds the backbone of flavor without screaming at you; fresh is always better than jarred here.
• Shredded cheddar cheese (200 g, 2 cups): Buy the block and shred it yourself if you can—the anti-caking agents in pre-shredded cheese sometimes interfere with the smooth sauce.
• Cream cheese (60 g, softened): This is your emulsifier and the thing that makes the sauce actually stick to everything instead of pooling at the bottom.
• Heavy cream (120 ml, 1/2 cup): The richness here is non-negotiable; don't water it down with milk or the whole thing loses its luxurious feel.
• Olive oil (1 tbsp): Just enough to bloom the garlic and release those volatile oils that make your kitchen smell alive.
• Salt, black pepper, smoked paprika, dried Italian herbs: Season generously because everything gets diluted by the cream—you're building flavor, not restraint.

Instructions

Set your stage:

Preheat the oven to 200°C (400°F) and lightly grease a medium baking dish. This 5 minutes of prep work is what separates a rushed dinner from one that feels intentional.

Soften the broccoli:

Steam or microwave the broccoli for 2 to 3 minutes until it's just tender but still bright green—you're aiming for al dente, not mushy. Drain it well because excess water is the enemy of a creamy sauce.

Build the base flavor:

Heat the olive oil in a skillet over medium heat, add the garlic, and sauté for exactly 1 minute. You'll know it's ready when the smell makes you pause and take a breath.

Combine everything:

In a large bowl, toss together the cooked chicken, steamed broccoli, sautéed garlic, half the cheddar, cream cheese, heavy cream, and all your seasonings. Fold gently until everything is coated and the cream cheese is distributed evenly, then transfer to your baking dish and top with the remaining cheese.

Bake until golden:

Bake for 20 to 25 minutes until the cheese on top is bubbly and just turning golden at the edges. A few dark brown spots are character, not a mistake.

Let it settle:

Give it 5 minutes of resting time before serving—this lets the sauce set and makes plating cleaner, though honestly, I've never waited and it's always been fine.

This dish turned into comfort food in a way I wasn't expecting, especially on the nights when eating keto felt like a chore. It reminded me that sometimes the simplest thing—cheese, protein, vegetables—can feel like kindness when you're tired and hungry.

Flavor Variations That Actually Work

The beauty of this casserole is that it's a canvas that welcomes small changes without falling apart. A pinch of red pepper flakes adds heat, grated Parmesan mixed into the sauce brings earthiness, and swapping half the broccoli for cauliflower creates subtle texture contrast. I've also stirred in crispy bacon bits at the last second and watched people's eyes light up, or added a splash of white wine to the cream mixture when I wanted something sharper and more refined.

Storage and Making It Ahead

This casserole actually tastes better the next day, which is rare and wonderful—the flavors integrate overnight and the cheese soaks into everything. You can assemble it fully, cover it, and refrigerate for up to 24 hours before baking, adding just 5 minutes to the cooking time. Leftovers keep for 3 to 4 days in an airtight container, and reheating gently in a 160°C oven keeps it creamy instead of dried out.

Serving Suggestions and Sides

This casserole is rich enough to stand alone, but it also plays beautifully with simple sides that won't complicate your macros. A crisp green salad with lemon vinaigrette cuts through the richness, or roasted Brussels sprouts alongside it creates a more substantial plate without adding carbs. Some nights I just add a pickle spear for brightness, or roasted garlic asparagus if I'm feeling ambitious.

• Pair it with a peppery arugula salad dressed in balsamic vinegar and olive oil.
• Serve alongside roasted zucchini slices seasoned with garlic and thyme for extra vegetables that won't derail ketosis.
• Keep it simple with just a wedge of lemon on the side if you're eating it straight from the dish on a busy weeknight.

This casserole has become my go-to proof that eating well doesn't mean eating boring food. It's the kind of dish that makes you feel taken care of, even when you're the one doing the cooking.
