Step-by-Step Instructions

Step 1: Prep That Cauli-Rice

Preheat your oven to 375°F. If using a whole cauliflower, chop it into florets and pulse in a food processor until it looks rice-like. The most important step? Pat that cauliflower rice DRY with paper towels! Seriously, nobody wants a soggy casserole.

Heat 1 tablespoon olive oil in a large skillet over medium heat, add your cauliflower rice with a pinch of salt and pepper, and cook for about 5-7 minutes until slightly tender but not mushy. Set aside and try not to snack on it (I always do).

Step 2: Make Your Chicken & Veggie Mix

In the same skillet (yay for fewer dishes!), heat the remaining tablespoon of olive oil. Add your chicken pieces and cook until they’re golden and just cooked through, about 5-6 minutes. Remove and set aside.

Now for the flavor base! Toss those diced onions into the hot skillet and cook until they’re soft and translucent. Add the garlic and cook just until fragrant – about 30 seconds. Don’t burn it or you’ll have to start over!

Add your bell peppers and mushrooms, cooking until everything is tender and starting to get those delicious browned edges. Sprinkle in all your herbs and spices, then add the chicken back to the pan and mix everything together. Your kitchen should smell amazing right about now!

Step 3: Whip Up The Creamy Sauce

In a separate saucepan, heat your olive oil or butter over medium heat. Add the almond flour and whisk constantly for 1-2 minutes. This is your arm workout for the day!

Gradually pour in your almond milk and chicken broth while continuing to whisk (no lumps allowed!). Bring to a gentle simmer, whisking frequently until the sauce begins to thicken enough to coat the back of a spoon.

Stir in that Dijon mustard (the secret ingredient!) and nutritional yeast. Fold in your chopped spinach and watch it wilt into beautiful green ribbons throughout your sauce. Season to taste – this sauce should make you want to lick the spoon!

Step 4: Layer It Up & Bake

Grab a 9×13 baking dish and give it a quick spray. Spread your cauliflower rice evenly across the bottom. Layer on your chicken and veggie mixture. Pour that creamy, dreamy sauce all over the top, making sure it seeps into all the nooks and crannies.

If you’re using cheese, sprinkle it on top now (or do half with, half without for mixed dietary needs). Pop it in the oven for 20-25 minutes until everything is bubbly and the top is getting golden in spots. Let it rest for 5 minutes before digging in!

Serving Suggestions

Serve this beauty straight from the oven with a bright, lemony side salad to cut through the richness. For non-low-carb eaters, some crusty whole grain bread on the side makes for happy dipping! And let’s be honest – a glass of crisp white wine pairs perfectly (it’s still healthy if the wine is dry, right?).

Clever Variations

Mediterranean Madness

Swap in Mediterranean herbs, add olives, sun-dried tomatoes, and top with feta cheese instead of mozzarella. Finish with fresh lemon zest for a bright pop!

Buffalo Chicken Twist

Add ⅓ cup buffalo sauce to your creamy mixture and use blue cheese instead of mozzarella. Top with sliced green onions and a drizzle of ranch if you’re feeling extra!

Tex-Mex Fiesta

Add a diced jalapeño, swap the herbs for taco seasoning, and throw in some black beans and corn. Top with pepper jack cheese and serve with avocado slices.

Broccoli Cheddar Chicken

Replace the spinach with small broccoli florets and use sharp cheddar instead of mozzarella for a kid-friendly version that still packs in the veggies!

Storage Solutions

This casserole is meal-prep magic! Once cooled, portion it into individual containers for grab-and-go lunches all week. It’ll keep in the fridge for 3-4 days.

For freezing, portion into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating tip: The oven gives you the best texture (350°F for about 15 minutes), but microwave works in a pinch (2-3 minutes) for those hangry moments!

Frequently Asked Questions

Can I use frozen cauliflower rice? Absolutely! Just make sure to thaw and squeeze out ALL the excess moisture first – that’s the key to avoiding cauliflower soup!

How do I make this dairy-free? Skip the cheese topping and use olive oil instead of butter. The nutritional yeast gives you that cheesy flavor without actual cheese.

My family hates cauliflower. Will they notice? The seasoning and sauce do an amazing job of disguising the cauliflower. If you’re really worried, try half cauliflower rice and half cooked quinoa as a starter!

Can I use rotisserie chicken to save time? YES! That’s my favorite shortcut on busy weeknights. Just shred about 3 cups and add it when you would return the cooked chicken to the pan.

Is this keto-friendly? You bet! The cauliflower rice keeps the carb count super low while still giving you that satisfying casserole experience.
