Ingredients for Roasted Garlic Cream Chicken Casserole

Here’s everything you’ll need to make this cozy, flavor-packed dish. I’ve included a few prep notes to make sure you’re set up for success:

• 1 head of garlic (roasted): Trust me, roasting it yourself makes all the difference. It’s sweeter, mellower, and just plain better than jarred stuff.
• 4 boneless, skinless chicken breasts (about 1.5 lbs): I like to slice them into smaller pieces for even cooking, but you can leave them whole if you prefer.
• 1 cup heavy cream (full-fat for richness): This is where the magic happens—don’t skimp on the creaminess!
• 1 cup shredded mozzarella cheese: Melty, gooey, and absolutely essential for that golden top.
• 1/2 cup grated Parmesan cheese: Adds a salty, nutty kick that balances the creaminess perfectly.
• 1 teaspoon dried thyme: Its earthy flavor pairs beautifully with the garlic.
• 1 teaspoon dried rosemary: A little goes a long way—this herb adds a warm, cozy note.
• 1 teaspoon salt: Season generously, but taste as you go—everyone’s preferences are different.
• 1/2 teaspoon black pepper: Freshly ground is best for that extra pop of flavor.
• 2 tablespoons olive oil: For roasting the garlic and searing the chicken—it’s a multitasker!

That’s it! Simple, right? Now let’s get cooking.

Equipment You’ll Need

You won’t need anything fancy for this recipe—just a few basics from your kitchen:

• A good skillet: For browning that chicken to golden perfection.
• 9×13-inch baking dish: The perfect size for layering everything together.
• Aluminum foil: Essential for wrapping that garlic before roasting—keeps it soft and caramelized.
• Mixing bowl: Where the roasted garlic and cream become best friends.

That’s it! Now let’s get to the fun part—making the casserole.

How to Make Roasted Garlic Cream Chicken Casserole

Alright, let’s dive into making this dreamy casserole! I’ll walk you through each step—it’s easier than you think, and the results are so worth it. Just follow along, and soon you’ll be savoring that first creamy, garlicky bite.

Step 1: Roast the Garlic

First things first—we need to transform that raw garlic into something magical. Preheat your oven to 375°F (190°C). Grab your whole head of garlic and slice about 1/4 inch off the top to expose all the cloves. Don’t worry about peeling them—they’ll pop right out later!

Drizzle the exposed cloves with about a tablespoon of olive oil, making sure every clove gets a little love. Then wrap the whole thing tightly in aluminum foil. This little garlic package goes right on the oven rack for 30 minutes. You’ll know it’s done when the cloves are golden brown and soft as butter when pressed.

Step 2: Sear the Chicken

While the garlic works its magic, let’s tackle the chicken. Heat the remaining tablespoon of olive oil in your skillet over medium-high heat. Season both sides of the chicken breasts generously with salt, pepper, thyme, and rosemary—this is where all that flavor starts building!

When the oil is shimmering (test it with a drop of water—if it sizzles, you’re ready), add the chicken. Cook for 4-5 minutes per side until you get that beautiful golden-brown crust. Don’t rush this step—that caramelization equals flavor! The chicken doesn’t need to be fully cooked through yet—it’ll finish in the oven.

Step 3: Assemble and Bake

Now for the fun part! Carefully unwrap your roasted garlic—careful, it’s hot! Squeeze the soft cloves into a bowl. They should pop right out of their skins. Mash them lightly with a fork, then stir in the heavy cream until smooth. This is your golden ticket to flavor town!

Arrange the seared chicken in your baking dish, then pour that luscious garlic cream over the top. Sprinkle first with mozzarella, then Parmesan—the two cheeses work together for maximum meltiness. Pop it in the oven (same 375°F temp) for 20-25 minutes, until the cheese is bubbly and golden brown. Your kitchen will smell incredible!

Let it rest for 5 minutes before serving—I know it’s hard to wait, but this helps the sauce thicken perfectly. Then dig in and enjoy the creamy, garlicky goodness!

Tips for the Best Roasted Garlic Cream Chicken Casserole

Want to take your casserole from good to unforgettable? Here are my tried-and-true secrets:

• Fresh herbs make all the difference: If you’ve got rosemary or thyme growing in your garden, use them! Just double the amount since fresh herbs are milder than dried.
• Patience pays off: Letting the casserole rest for 5 minutes after baking lets the creamy sauce thicken perfectly—no runny mess!
• Taste as you go: Garlic sizes vary, so adjust salt at the end. I always sneak a spoonful of the cream mixture before baking to check seasoning.

Ingredient Substitutions

Look, I get it—sometimes you need to swap things based on what’s in your fridge or dietary needs. Here are my favorite substitutions that still keep this casserole delicious:

• Half-and-half instead of heavy cream: It’ll still be creamy, just slightly less rich. If you go this route, add an extra tablespoon of Parmesan to help thicken the sauce.
• Turkey breast for chicken: Works beautifully! Just watch the cooking time—turkey tends to dry out faster, so check it at 15 minutes.
• Vegan cheese alternatives: My lactose-intolerant friend swears by almond-based mozzarella. The melt isn’t quite as stretchy, but the flavor still hits the spot.
• Fresh garlic in a pinch: If you’re truly desperate, use 2 teaspoons of minced raw garlic—but honestly, roasted is worth the wait.

A quick heads-up: swapping more than two ingredients changes the character of the dish. The original is perfection, but life happens—so adapt away!

Serving Suggestions

This casserole is a meal on its own, but I love pairing it with garlic bread for extra indulgence or a simple side of steamed broccoli to balance the creaminess. A crisp green salad works wonders too!

Storage and Reheating

Leftovers? No problem—this casserole keeps like a dream! Just let it cool completely (I know, patience is hard when it smells this good), then cover tightly with foil or transfer to an airtight container. It’ll stay fresh in the fridge for up to 3 days. Want to freeze it? Hold the cream sauce—make everything up to the baking step, then freeze the assembled (but unbaked) dish for up to 2 months. Thaw overnight in the fridge before baking as usual.

When reheating, the oven is your best friend—it keeps that creamy texture perfect. Pop individual portions in a 350°F oven for 15-20 minutes until warmed through. If you’re in a real rush, the microwave works in a pinch (30-second bursts, stirring in between), but fair warning: the cheese gets rubbery and the sauce might separate a bit. Your taste buds deserve better!

Nutritional Information

Now, I’m no nutritionist, but here’s the general breakdown per serving—just so you know what you’re diving into with this glorious casserole! Keep in mind these numbers can vary depending on your exact ingredients (like how much cheese you actually sprinkle on—we all know measurements go out the window when cheese is involved).

• Calories: Around 450
• Fat: 28g (14g saturated—that’s the cream and cheese working their magic)
• Protein: 40g (thank you, chicken!)
• Carbs: 6g (mostly from the garlic—who knew?)

This isn’t diet food, folks—it’s comfort food. And sometimes, that’s exactly what your soul needs. Everything in moderation, right? Now go enjoy every creamy, garlicky bite!

FAQs About Roasted Garlic Cream Chicken Casserole

I get asked about this recipe all the time—here are the answers to the most common questions that pop up in my kitchen (and my inbox!):

Can I use garlic powder instead of roasting fresh garlic?
Oh honey, I wish I could say yes—but trust me, it’s not the same. Garlic powder gives you that sharp, one-note garlic punch, while roasted garlic brings sweetness, depth, and richness you just can’t replicate. That said, if you’re truly in a pinch, use 2 teaspoons of garlic powder mixed right into the cream. It’ll work, but your taste buds will know the difference!

Can I freeze this casserole?
Absolutely! Here’s my trick: assemble everything except the cream sauce—just layer the seared chicken and cheeses in your baking dish, then wrap it tightly in plastic and foil. Freeze for up to 2 months. When you’re ready, thaw overnight in the fridge, mix up your roasted garlic cream fresh (this part only takes 5 minutes!), pour it over, and bake as usual. The texture stays perfect this way—no grainy or separated sauce!

How can I make this spicier?
Ooooh, I love this question! My go-to is 1/2 teaspoon of crushed red pepper flakes mixed into the cream sauce—it gives the perfect slow burn that plays so nicely with the garlic. For serious heat lovers, add a diced jalapeño when searing the chicken (seeds and all!). Just warn your dinner guests—this turns cozy comfort food into a fiery delight!
