I have to confess, this beloved recipe started not with a grand plan, but with a classic “What-on-earth-is-in-my-fridge?” moment. It was a chilly Tuesday evening, the kind where the wind was howling and the only thing on my mind was a big, warm, cheesy casserole. I had a whole roasted chicken from the night before, a bag of cauliflower rice I needed to use up, and a jar of red pesto staring back at me from the fridge door.

My husband, Mark, peeked into the kitchen, drawn by the sizzle of garlic in olive oil. “What’s the masterpiece tonight?” he asked, always my most enthusiastic taste-tester. I laughed and said, “Either a masterpiece or a magnificent mess!” I started tossing things together, guided purely by instinct and a serious craving. When I pulled that golden, bubbling dish out of the oven, the smell was absolutely intoxicating. We dug in right away, standing over the stove because we couldn’t wait. One bite, and we looked at each other with wide eyes. It was a total home run. My daughter, who usually eyes anything green with suspicion, asked for seconds. That’s when I knew this happy accident was destined to become a permanent part of our family’s recipe rotation.

Gathering Your Kitchen Crew: The Ingredients

Here’s the beautiful part: this dish is all about simplicity and flexibility. Let’s walk through the cast of characters that make this bake so unforgettable. Don’t stress if you’re missing something—I’ve got plenty of substitution ideas for you!

  • 2 cups cooked, shredded chicken: This is the perfect way to use up leftover rotisserie chicken or last night’s roasted chicken! It adds lean protein and makes the dish incredibly satisfying. Chef’s Tip: No leftover chicken? No problem! You can quickly poach two chicken breasts, or for a super-fast option, use a high-quality canned or pre-cooked shredded chicken.
  • 3 cups cauliflower rice (fresh or frozen): Our low-carb hero! It creates the perfect, fluffy base that soaks up all the wonderful flavors. Chef’s Insight: If using frozen, there’s no need to thaw it completely, but do let it sit out for a few minutes and give it a good squeeze in a clean kitchen towel to remove excess moisture. This prevents a watery bake!
  • 2 tbsp red pesto: This is the flavor powerhouse! It brings a punch of herby, garlicky, slightly nutty depth that ties everything together. Substitution Tip: Don’t have red pesto? A good tablespoon of tomato paste mixed with a teaspoon of Italian seasoning and a pinch of garlic powder can work in a pinch.
  • 1 medium tomato, diced: It adds a lovely pop of freshness and a slight acidity that cuts through the richness. I love the little bursts of flavor!
  • 2 cloves garlic, minced: Because is there anything better than the smell of garlic sizzling in olive oil? It’s the aromatic foundation of our dish.
  • 1 cup shredded mozzarella: For that iconic, melty, stretchy cheese pull we all dream about. I like to use a low-moisture, part-skim mozzarella for the best melt.
  • 1 cup arugula (or spinach): A sneaky way to get in some greens! They wilt down beautifully and add a lovely, slightly peppery note. Chef’s Insight: Don’t be shy to pack it in—it wilts down to almost nothing!
  • 2 tbsp fresh dill, chopped: This is my secret weapon! Dill has a bright, grassy flavor that pairs amazingly well with the chicken and pesto. It makes the whole dish taste fresh and vibrant. Substitution Tip: If you’re not a dill fan, fresh parsley or basil would be lovely here.
  • 2 tbsp olive oil: For sautéing our garlic and cauliflower rice to perfection.
  • ¼ cup milk (any kind): Just a splash! This helps create a creamy, cohesive sauce that binds everything together without being heavy. I’ve used everything from whole milk to unsweetened almond milk, and it works beautifully every time.
  • Salt & pepper, to taste: The essential seasonings that make all the other flavors pop. Don’t forget to taste as you go!

Let’s Get Cooking: Step-by-Step Instructions

Ready to see how this all comes together? It’s a straightforward process, but I’ve packed each step with my favorite little chef hacks to ensure your bake turns out perfectly every single time.

  1. Preheat & Prep: First things first, get that oven going! Preheat it to 375°F (190°C). While it’s warming up, lightly grease your favorite 9×9-inch (or similar) baking dish with a bit of olive oil or non-stick spray. Chef’s Hack: Doing this now means your baking dish is ready to go the second your skillet mixture is done. No frantic searching while your hands are full!
  2. Sizzle Your Aromatics: Place a large skillet over medium heat and add your two tablespoons of olive oil. Once the oil is shimmering, add the minced garlic. We’re not looking to brown it, just to wake it up and fill your kitchen with that incredible fragrance. Sauté for about 30-60 seconds until it’s fragrant. Chef’s Tip: Be careful not to burn the garlic! Burnt garlic turns bitter, and we want all that lovely, mellow flavor.
  3. Cook the Cauliflower Rice: Now, add all three cups of cauliflower rice to the skillet. Give it a good stir to coat it in the garlicky oil. Let it cook for 4-5 minutes, stirring occasionally. You’re looking for it to soften up and maybe take on a tiny bit of color. Chef’s Insight: This step is crucial for driving off excess moisture and developing the cauliflower’s flavor, so don’t rush it!
  4. The Big Mix-In: This is the fun part! To the skillet, add your diced tomato, red pesto, shredded chicken, arugula (or spinach), fresh dill, that splash of milk, and a generous pinch of salt and pepper. Stir everything together until it’s beautifully combined and the arugula has just started to wilt. Let it cook for another 2-3 minutes until the entire mixture is warmed through. Chef’s Hack: This is your final chance to taste the mixture before it goes in the oven. Give it a try and adjust the seasoning if needed. Remember, the flavors will meld and intensify a bit in the oven, so trust your palate!
  5. Top & Bake: Carefully transfer the warm, flavorful mixture from your skillet into your prepared baking dish. Spread it out into an even layer. Now, for the grand finale: sprinkle that entire cup of shredded mozzarella cheese evenly over the top. Chef’s Tip: For an extra-golden, bubbly top, you can add a tiny sprinkle of Parmesan cheese over the mozzarella. Pop the dish into your preheated oven and bake for 15-20 minutes. You’re waiting for that gorgeous, bubbly, golden-brown cheese crust to form.
  6. The Most Important Step: Rest! I know, I know—it’s tempting to dive right in! But trust me on this one. Pull the bake out of the oven and let it sit on the stovetop for about 5-7 minutes before serving. Chef’s Hack: This resting time allows the flavors to settle and the bake to firm up just enough so you get perfect, clean slices instead of a saucy puddle. It’s a game-changer!

Plating Up Your Masterpiece

How you serve this bake can turn a simple weeknight dinner into a little event! I love serving it right from the baking dish at the table for a cozy, family-style feel. Use a large spoon to scoop out generous portions. For a beautiful plate, garnish with an extra sprinkle of fresh dill and a few extra arugula leaves for a fresh, peppery contrast. This dish is a complete meal on its own, but it’s also wonderful with a simple side salad tossed in a light vinaigrette to balance the richness, or with some crusty, warm bread for those who aren’t watching their carbs.

Make It Your Own: Recipe Variations

The beauty of this recipe is its adaptability! Feel free to get creative and make it suit your taste or what you have on hand.

  • Spicy Kick: Add a pinch of red pepper flakes with the garlic, or stir in a tablespoon of chopped jalapeños for a little heat.
  • Mediterranean Twist: Swap the mozzarella for crumbled feta cheese and add a handful of chopped Kalamata olives and a teaspoon of dried oregano.
  • Mushroom Lover’s Dream: Sauté 8 oz of sliced cremini mushrooms with the garlic until golden brown before adding the cauliflower rice.
  • Dairy-Free Delight: Use a vegan mozzarella shreds and swap the milk for unsweetened plant-based milk. The pesto is usually dairy-free, but always double-check the label!
  • Turkey or Tuna Swap: Don’t have chicken? Shredded turkey or two cans of well-drained tuna are fantastic alternatives.

Anna’s Chef’s Notes

This recipe has truly evolved in our kitchen. My daughter now calls it “Mom’s Magical Green Chicken,” which always makes me laugh (I think it’s the dill and pesto!). Over time, I’ve found that the type of pesto you use can really change the character of the dish. I’ve experimented with sun-dried tomato pesto for a deeper flavor, and even a kale-based pesto, and both were delicious. The core of the recipe is wonderfully forgiving. I also love making a double batch and freezing one before the baking step. It’s like a gift to my future self on a crazy day—just thaw it in the fridge and then bake as directed. It’s a recipe that truly gives back, and that’s my favorite kind.

Your Questions, Answered!

I’ve gotten so many wonderful questions about this bake over time. Here are the most common ones to help you out!

Q: My bake turned out a bit watery. What happened?
A: This is almost always due to excess moisture in the cauliflower rice! Frozen cauliflower rice is a major culprit. My best tip is to squeeze it dry in a clean kitchen towel after it’s thawed. Even fresh cauliflower rice can hold a lot of water. Sautéing it well in the skillet (Step 3) is your first line of defense to drive off that moisture.

Q: Can I make this entire dish ahead of time?
A> Absolutely! You are a meal-prep genius. Assemble the entire bake right up to the point of topping it with cheese. Cover it tightly and store it in the fridge for up to 24 hours. When you’re ready, just pop it in the oven. You might need to add an extra 5-10 minutes to the baking time since it’s going in cold.

Q: I’m not a fan of dill. What other herbs would work?
A> No problem at all! Dill has a distinct flavor, and it’s not for everyone. Fresh parsley is a fantastic, neutral substitute. Fresh basil would be incredible and play beautifully with the pesto. If you only have dried herbs, use about one teaspoon of dried parsley or Italian seasoning.

Q: Is there a way to make this without a skillet?
A> You bet! If you want to minimize dishes, you can mix everything (except the cheese) in a large bowl. Combine the raw cauliflower rice, chicken, pesto, tomato, garlic (minced, not sautéed), arugula, dill, milk, and olive oil. Mix well, transfer to the baking dish, top with cheese, and bake. The texture will be slightly different as the garlic and cauliflower won’t be sautéed first, but it will still be utterly delicious! Just bake for a few minutes longer, around 25-30 minutes.
