There’s something truly special about a warm, bubbling casserole that feels like a hug on a plate — and this one is no exception. The top gets wonderfully golden and slightly crisp while the inside stays luscious and creamy, studded with tender chicken and vibrant little florets of broccoli and cauliflower; it’s a symphony of textures and comfort. Honestly, it’s a staple in my kitchen when I want something satisfying without fuss, especially on chilly weeknights.
It comes together surprisingly fast, which is a blessing on busy evenings, and it holds up beautifully for lunches the next day (if there are any!). It’s also flexible — dress it up for guests or keep it humble for a family night — and if you want a playful weekend contrast, try my chicken waffles with blueberry syrup for a fun pairing that everyone remembers.
WHY I LOVE Low Carb Chicken Casserole
I love this Low Carb Chicken Casserole because it hits that sweet spot between comfort and cleverness — creamy, cheesy, and not weighed down by starch. It’s incredibly easy and undeniably delicious, with the veggies lending a fresh lift to the rich custard. Versatile? Absolutely — it’s just as happy on a kid-friendly dinner table as it is on a Sunday supper spread where you want to look like you tried. This is a true winner at my table, every time.
Low Carb Chicken Casserole INGREDIENTS
The magic of this Low Carb Chicken Casserole truly lies in how simple ingredients mingle to create something greater than the sum of its parts — tender bites of chicken, crisp-tender broccoli and cauliflower, and a silky, savory custard that holds it all together. Don’t worry about exact measurements just yet; those are all in the recipe card for you!
Core Ingredients and Their Roles
- COOKED CHICKEN, SHREDDED: 2 cups — The star protein; brings tenderness and a savory foundation to every forkful. These are the stars!
- BROCCOLI FLORETS: 1 cup — Adds bright color and a slight snap that balances the creaminess; little gems pack a mighty punch.
- CAULIFLOWER FLORETS: 1 cup — Subtle, nutty, and great at soaking up the custard; it helps keep the dish low-carb while feeling hearty.
- SHREDDED CHEESE (CHEDDAR OR MOZZARELLA): 1 cup — Melts into gooey pockets and creates that irresistible golden top; choose sharper cheddar for more tang.
- HEAVY CREAM: 1 cup — The luxe binder that makes the filling silky and indulgent (though rich, it’s key to the texture).
- EGGS: 2 — Act as the set for the casserole, giving structure and a custardy finish.
- GARLIC POWDER: 1 teaspoon — For background warmth and savory depth.
- ONION POWDER: 1 teaspoon — Rounds out the aromatics without extra chopping.
- SALT AND PEPPER: To taste — Simple seasoning that brings everything together (don’t skimp!).
SUBSTITUTIONS AND TIPS
Need a swap? Here are a few friendly options:
- Swap heavy cream with half-and-half or a mix of cream and chicken broth — though it won’t be quite as rich, you’ll still get a lovely custard (add a tablespoon of butter if you want extra silkiness).
- Use cooked shredded turkey instead of chicken for a post-holiday twist; flavor profile is similar but slightly drier, so a touch more cream can help.
- Try Gruyère or a pepper jack in place of cheddar for a different character — Gruyère brings nuttiness, pepper jack adds a little kick.
- For extra veggie variety, toss in a handful of spinach (squeeze out excess moisture) or substitute cauliflower with zucchini slices (reduce bake time slightly).
Practical tips: let the casserole rest a few minutes after baking so it firms up (this helps for clean slices), and if your florets are large, chop them smaller so every bite is balanced.
KITCHEN TOOLS YOU’LL NEED
- 9×9 or similar-size baking dish (about 2-quart capacity)
- Large mixing bowl (3-4 quarts)
- Medium bowl for whisking wet ingredients
- Whisk (or fork) for eggs and cream
- Measuring cups and spoons (liquid measuring cup recommended)
- Cheese grater (if grating your own cheese)
HOW TO MAKE Low Carb Chicken Casserole
Let’s dive into creating this cozy Low Carb Chicken Casserole. I’ve broken down the process into simple steps. Follow along, and you’ll have a delicious meal in no time. We’re aiming for a set, golden-topped casserole with a creamy interior that isn’t soupy.
Layer for Maximum Flavor
First, preheat the oven to 375°F (190°C). This step ensures the dish starts at the right temperature so the custard sets evenly — preheating is key for that nicely browned top.
Combine the Proteins and Veggies
Next, in a large mixing bowl, combine the cooked chicken, broccoli, cauliflower, and half of the cheese. Give everything a gentle toss so the cheese starts to cling to the chicken and vegetables; this helps distribute flavor and texture throughout the bake.
Mix Wet Ingredients Until Silky
Now, in another bowl, whisk together the heavy cream, eggs, garlic powder, onion powder, salt, and pepper. Whisk until smooth and slightly frothy — this is the binder that will turn into a luscious custard, so take a moment to make it uniform.
Bring Everything Together
Pour the cream mixture over the chicken and vegetable mixture and stir to combine. Make sure every bit of chicken and veg gets a little of that creamy goodness; this is the moment flavors marry, so give it a good stir.
Assemble in the Baking Dish
Transfer the mixture to a greased baking dish and top with the remaining cheese. Spread it into an even layer (press gently if needed) so the heat reaches everything evenly and the top browns beautifully.
Bake Until Bubbly and Set
Bake for 35-40 minutes or until the casserole is set and the cheese is golden. You’re looking for the custard to no longer be jiggly in the center and for a light golden crust on top — that crust is where the deep flavor lives!
Rest Before Serving
Let it cool slightly before serving. This short rest (about 5-10 minutes) helps the casserole firm up for easier slicing and gives the flavors a chance to settle — you’ll notice the texture becomes wonderfully cohesive.
HOW TO STORE Low Carb Chicken Casserole
Leftovers keep nicely — the casserole holds texture well and tastes even better the next day. At room temperature, don’t leave it out for more than 2 hours. Store in an airtight container in the refrigerator for 3–4 days. You can freeze portions for up to 2–3 months; thaw overnight in the fridge before reheating. Reheat gently in a 350°F oven until warmed through, or microwave individual portions on medium power, stirring halfway.
TIPS FOR SUCCESS
- Use evenly sized florets. This ensures broccoli and cauliflower cook through at the same rate.
- Shred or chop cooked chicken into similar-sized pieces so every bite is balanced.
- Don’t overfill the dish; leave a bit of space so the custard can expand slightly without spilling.
- Let the casserole rest before cutting to avoid a runny center.
- If you like a crispier top, broil for 1–2 minutes at the end — watch closely!
SERVING SUGGESTIONS
- Serve with a simple green salad dressed in lemon vinaigrette to cut the richness.
- Brighten the plate with roasted cherry tomatoes or a side of sautéed green beans.
- Pair with a crisp white wine like Sauvignon Blanc or a light, citrusy beer.
- Garnish with chopped fresh parsley or chives for color and a fresh note.
- Present in individual ramekins for a charming, oven-to-table look.
