A creamy, cheesy keto chicken broccoli casserole ready in 25 minutes. This one-pan meal features tender chicken and broccoli in a rich garlic Alfredo sauce with only 4.5g net carbs per serving.
Ingredients
- 2 tbsp 28.4 g butter, divided (unsalted preferred)
- 16 oz 453.59 g broccoli florets, coarsely chopped (fresh)
- 4 cloves garlic minced
- 3/4 cup 177.44 ml heavy whipping cream (full-fat only)
- 1 1/3 cups 149.33 g shredded mozzarella cheese, divided (freshly shredded)
- 1/3 cup 33.33 g grated Parmesan cheese (freshly grated)
- Salt and pepper to taste
- 1 1/2 lb 680.39 g cooked chicken, chopped (about 4 cups)
Instructions
- Prepare the broccoli:
- Melt 1 tablespoon of butter in a large oven-safe skillet over medium-high heat.
- Add the chopped broccoli florets and sauté for 4-5 minutes, stirring occasionally, until bright green and just tender.
- Transfer the sautéed broccoli to a bowl and set aside.
- Create the garlic cream sauce:
- Add the remaining tablespoon of butter to the same skillet and let it melt completely over medium heat.
- Add the minced garlic and sauté for 30-45 seconds until fragrant (don't let it brown).
- Pour in the heavy whipping cream, increase heat slightly, and bring to a gentle simmer.
- Let the cream reduce by about half, stirring occasionally, for 3-4 minutes.
- Incorporate the cheeses:
- Lower the heat to medium-low.
- Add 1 cup of the shredded mozzarella and all the Parmesan cheese.
- Stir continuously until the cheeses melt completely into the cream (about 2 minutes).
- Season with salt and pepper to taste (about 1/2 teaspoon salt and 1/4 teaspoon pepper).
- Combine everything:
- Add the cooked chicken and sautéed broccoli back into the skillet.
- Stir everything together until evenly coated with the creamy cheese sauce.
- Spread the mixture evenly in the pan.
- Sprinkle the remaining 1/3 cup of mozzarella cheese over the top, covering the entire surface.
- Broil to perfection:
- Turn your oven's broiler to high and position the oven rack about 6 inches from the heating element.
- Place the skillet under the broiler and watch carefully.
- Broil for 2-3 minutes until the cheese is bubbly with golden-brown spots.
- Remove from oven and let cool for 2-3 minutes before serving.
Notes
Oven-safe skillet: Use a cast iron or any heavy-bottomed oven-safe skillet. Check that your pan's handle can withstand broiler heat.
Using frozen broccoli: Thaw completely and squeeze out excess moisture. Skip the sautéing step and add the drained broccoli directly in step 4.
Storage: Store leftovers in an airtight container in the refrigerator for 3-4 days. Reheat in microwave for 1-2 minutes or in a 350°F oven for 15-20 minutes covered.
