Ingredients

Here’s what you’ll need to make your own Keto Cheesy Crockpot Chicken and Broccoli Casserole, and I’ll share a few pantry secrets along the way:
- 3 large boneless, skinless chicken breasts (I always grab fresh, organic if I can for the best flavor and tender texture in my Keto Cheesy Crockpot Chicken and Broccoli Casserole)
- 4 cups fresh broccoli florets (frozen works too, but fresh makes the dish pop and keeps that nice green color)
- 1 ½ cups shredded sharp cheddar cheese (my go-to for its sharp flavor in this cheesy chicken dinner)
- 1 cup shredded mozzarella cheese (adds that beautiful melt, making this keto casserole recipe extra creamy)
- 1 cup heavy cream (you can find this in the dairy aisle—full fat is crucial for that luscious sauce)
- 1/2 cup mayonnaise (trust me, it adds richness without overpowering your Keto Cheesy Crockpot Chicken and Broccoli Casserole)
- 2 cloves garlic, minced (because garlic and chicken are best friends—always fresh if you have it!)
- 1 teaspoon onion powder
- 1 teaspoon Dijon mustard (optional, but I love how it sneaks in a little tang)
- Salt and freshly ground black pepper to taste
A little tip from my own kitchen wisdom: When making Keto Cheesy Crockpot Chicken and Broccoli Casserole, I always prep my broccoli while the chicken browns quickly in a skillet. It’s a time saver, especially on hectic days. And here’s a trick I learned from my mom—wear disposable gloves when handling garlic to save your nails from lingering smells! You can find most of these ingredients at your local grocery store’s fresh and dairy aisles. For a little cost-saving hack, buy cheddar blocks and shred your cheese at home—it’s cheaper and melts better for this low carb chicken casserole.
Got leftovers? You’ll want to store any unused shredded cheese in an airtight container and keep your broccoli in the fridge in a sealed bag to maintain freshness for several days. This way, making a second batch of this slow cooker broccoli chicken dish is even faster!

How to Make Keto Cheesy Crockpot Chicken and Broccoli Casserole – Step-by-Step
Alright, let’s roll up our sleeves and make this classic Keto Cheesy Crockpot Chicken and Broccoli Casserole happen. Don’t worry if your kitchen gets a little messy—that’s where the fun is!
- Step 1: Start by seasoning your chicken breasts with salt, pepper, garlic, and onion powder. I like to toss in a splash of olive oil to help the seasoning stick. This small step really builds flavor in your keto casserole recipe.
- Step 2: In a skillet over medium heat, brown the chicken breasts for about 3-4 minutes on each side. This seals in the juices. Don’t fret if you can’t get a perfect sear; just make sure the color is nice—it won’t be fully cooked yet because the slow cooker finishes everything perfectly.
- Step 3: While the chicken cooks, chop up your broccoli florets if you haven’t done so. I love doing this while stirring that quick skillet chicken—it saves time.
- Step 4: Spray the inside of your slow cooker with a little cooking spray or butter to prevent sticking. Arrange the browned chicken breasts in the bottom, then layer on the broccoli.
- Step 5: Now for our creamy cheesy sauce. In a mixing bowl, combine the mayonnaise, heavy cream, shredded cheddar, shredded mozzarella, and Dijon mustard. Stir everything until creamy and combined. This is what turns your slow cooker broccoli chicken into pure keto delight.
- Step 6: Pour the cheese mixture over the chicken and broccoli evenly. Pop the lid on your crockpot.
- Step 7: Set your slow cooker to low and cook for 4-6 hours. My kitchen always starts to smell like comfort and heaven around the 3-hour mark. If you get worried it’s not looking “done,” remember the chicken is cooking gently and will shred beautifully at the end.
- Step 8: About 30 minutes before serving, I like to take the lid off and sprinkle extra cheese on top for a nice melty finish. Then cover again and let it melt into a gooey topping.
- Step 9: When it’s ready, check that the internal temp of the chicken reaches 165°F to be safe. Then, shred the chicken right in the slow cooker with two forks and stir everything together. That mix of tender chicken, cheesy sauce, and broccoli is so satisfying!
While the Keto Cheesy Crockpot Chicken and Broccoli Casserole cooks, I usually tidy up the kitchen, start prepping any sides, or just enjoy a quiet moment with a cup of tea.

Serving Keto Cheesy Crockpot Chicken and Broccoli Casserole

Serving this Keto Cheesy Crockpot Chicken and Broccoli Casserole is always a highlight in my house. The kids love how creamy and cheesy it is – it’s like their favorite cheesy chicken dinner but sneakily packed with broccoli and low carb goodness. I like to spoon it straight onto plates and let the cheese sauce be the star.
For a perfect pairing, I often serve it with a light side salad, maybe some garlic butter sautéed mushrooms, or roasted cauliflower rice. These sides keep the meal keto-friendly and add a nice texture contrast. Plus, it rounds out the crockpot healthy meal perfectly.
This casserole is great for weeknight dinners, but it’s also fantastic for casual get-togethers or potlucks because you can keep it warm in the slow cooker until guests arrive. One time, I brought a batch to a family holiday lunch, and my cousins begged me to share the recipe (a win in slow cooker broccoli chicken!).
If you find yourself with leftovers (and sometimes, there are almost never leftovers—but just in case), I’ve reheated this casserole in the oven covered to keep the cheese from drying out. It reheats nicely, and sometimes I add a little extra shredded cheese on top for a second round of melty goodness. You can also serve leftover Keto Cheesy Crockpot Chicken and Broccoli Casserole over zucchini noodles or as a filling for keto wraps for a quick lunch.
