Ingredients You’ll Need

Gathering ingredients for your Kentucky Hot Brown Casserole is straightforward. Most items are pantry staples, making this recipe wonderfully accessible. Here’s what you’ll need:

Ingredient	Quantity
Cooked turkey breast, cubed or shredded	4 cups
Thick-cut bacon	12 slices
Butter	4 tablespoons
All-purpose flour	4 tablespoons
Whole milk	2 cups
Heavy cream	1 cup
Parmesan cheese, grated	1 cup
Sharp cheddar cheese, shredded	1 cup
Garlic powder	1 teaspoon
Onion powder	1 teaspoon
Salt and black pepper	To taste
Roma tomatoes, sliced	3 medium
Fresh parsley, chopped	2 tablespoons
Bread cubes (optional topping)	2 cups

These simple ingredients combine to create the signature richness of a Kentucky Hot Brown Casserole. The Mornay sauce is the star, so don’t skimp on quality cheese.

Substitutions & Variations

One reason we love this Kentucky Hot Brown Casserole is its flexibility. You can easily adapt it to suit your preferences or what’s in your refrigerator.

Instead of turkey, try rotisserie chicken. It works beautifully and saves time. Alternatively, leftover Thanksgiving turkey makes this casserole shine even brighter.

For a lighter version, substitute half-and-half for heavy cream. The sauce stays creamy while reducing calories slightly.

Don’t eat pork? Skip the bacon and add smoked paprika for that smoky depth. Henry actually prefers turkey bacon sometimes, and it works perfectly fine.

For cheese variations, swap cheddar with Gruyere for a more sophisticated flavor. Some folks add a splash of white wine to the Mornay sauce for extra richness.

Want to add vegetables? Sautéed mushrooms or spinach fold beautifully into this Kentucky Hot Brown Casserole. For a carb-conscious option, skip the bread cubes entirely.

The casserole still tastes incredible without them. Finally, experiment with different tomato varieties. Cherry tomatoes halved make a sweeter, prettier presentation.

Step-by-Step Instructions

Making this Kentucky Hot Brown Casserole is easier than you think. Follow these simple steps, and you’ll have a restaurant-worthy dish on your table.

Step 1: Preheat your oven to 375°F. Grease a 9×13-inch baking dish generously with butter or cooking spray.

Step 2: Cook bacon in a large skillet until crispy. Transfer to paper towels to drain, then crumble into pieces. Set aside for topping your Kentucky Hot Brown Casserole later.

Step 3: In a medium saucepan, melt butter over medium heat. Once melted, whisk in flour constantly for about 2 minutes. This creates your roux base.

Step 4: Gradually pour in milk and cream while whisking continuously. Keep stirring until the mixture thickens, approximately 5-7 minutes. The sauce should coat the back of a spoon nicely.

Step 5: Reduce heat to low. Add Parmesan cheese, half the cheddar, garlic powder, onion powder, salt, and pepper. Stir until cheese melts completely into a smooth Mornay sauce.

Step 6: Place cubed turkey in the prepared baking dish. Pour the creamy Mornay sauce evenly over the turkey. Gently stir to coat everything thoroughly.

Step 7: Arrange tomato slices on top. Sprinkle remaining cheddar cheese, then add crumbled bacon. If using bread cubes, toss them in melted butter and scatter over the Kentucky Hot Brown Casserole.

Step 8: Bake uncovered for 25-30 minutes. The casserole should bubble around the edges, and the top should turn golden brown.

Step 9: Remove from oven and let rest for 5 minutes. Garnish with fresh parsley before serving your beautiful Kentucky Hot Brown Casserole.

Pro Tips for Success

After making this Kentucky Hot Brown Casserole dozens of times, Henry and I have learned some tricks. These tips ensure perfect results every single time.

First, don’t rush the roux. Cooking the flour and butter properly prevents a raw flour taste in your sauce. Stir constantly and let it bubble gently for the full two minutes.

Second, use room temperature dairy. Cold milk creates lumps in your Mornay sauce. Let milk and cream sit out for 30 minutes before starting. This simple step makes whisking so much easier.

Third, shred your own cheese. Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Freshly grated Parmesan and cheddar create a silkier sauce for your Kentucky Hot Brown Casserole.

Fourth, don’t overbake. Once the casserole bubbles and turns golden, it’s done. Overbaking dries out the turkey and makes the sauce grainy. Watch it closely during the final minutes.

Finally, let it rest before serving. Those five minutes allow the sauce to thicken slightly. Your Kentucky Hot Brown Casserole will slice more neatly and taste even better. Patience pays off here.

Storage & Reheating Tips

Leftover Kentucky Hot Brown Casserole stores beautifully, making it perfect for meal prep. Here’s how to keep it fresh and delicious.

Store cooled casserole in an airtight container in the refrigerator. It stays fresh for up to 3-4 days. The flavors actually deepen overnight, so leftovers taste fantastic. For longer storage, freeze individual portions in freezer-safe containers for up to 3 months.

When reheating, oven method works best. Cover the Kentucky Hot Brown Casserole with foil and bake at 350°F for 20-25 minutes until heated through. This preserves the creamy texture beautifully.

Microwave works in a pinch for single servings. Heat on medium power in 1-minute intervals, stirring between each. Add a splash of milk if the sauce seems too thick. The bacon might lose some crispness, but the flavor remains wonderful.

Avoid refreezing previously frozen casserole. Quality deteriorates with multiple freeze-thaw cycles. Instead, freeze in portion sizes you’ll use in one sitting. Your future self will thank you when quick comfort food is just a reheat away.

What to Serve With This Recipe

This Kentucky Hot Brown Casserole is hearty and rich, so lighter sides balance the meal perfectly. We love pairing it with simple, fresh accompaniments.

A crisp green salad with tangy vinaigrette cuts through the richness beautifully. Henry tosses mixed greens with lemon juice, olive oil, and a touch of Dijon mustard. The brightness complements the creamy casserole wonderfully.

Roasted asparagus or green beans add color and nutrition. Simply toss with olive oil, salt, and pepper, then roast until tender-crisp. The slight char flavor pairs excellently with the Kentucky Hot Brown Casserole.

For a Southern twist, serve cornbread on the side. The slightly sweet bread soaks up extra Mornay sauce deliciously. Coleslaw also works great, adding crunch and acidity to each bite.

Cranberry sauce provides a sweet-tart contrast that reminds us of Thanksgiving. It’s especially fitting since this casserole often features leftover holiday turkey. Finally, a glass of crisp white wine or sweet tea completes this comforting meal perfectly.

FAQs

Can I make Kentucky Hot Brown Casserole ahead of time?

Absolutely! Assemble your Kentucky Hot Brown Casserole completely, cover tightly with foil, and refrigerate up to 24 hours before baking. Add 10 extra minutes to the baking time since it starts cold. This make-ahead feature makes it perfect for entertaining or busy weeknights.

What makes a Hot Brown different from regular turkey casserole?

The Kentucky Hot Brown features a signature Mornay sauce—a cheese-enriched béchamel. Additionally, bacon and tomatoes are essential components. The original was created at Louisville’s Brown Hotel in the 1920s. Our casserole version maintains these classic elements while making it easier to serve crowds.

Can I use deli turkey for this recipe?

Yes, thick-sliced deli turkey works in your Kentucky Hot Brown Casserole. Choose quality, low-sodium turkey breast and cube it into bite-sized pieces. However, roasted turkey breast provides better flavor and texture. Rotisserie chicken is another excellent option if turkey isn’t available.

How do I prevent the sauce from becoming grainy?

Keep heat moderate when making your Mornay sauce. High heat causes cheese proteins to seize and become grainy. Also, use freshly grated cheese rather than pre-shredded.

Add cheese off heat or on very low heat, stirring constantly until smooth. These steps ensure your Kentucky Hot Brown Casserole has perfectly creamy sauce.

Can I freeze Kentucky Hot Brown Casserole?

Yes, this casserole freezes reasonably well for up to 3 months. However, cream-based sauces sometimes separate slightly when frozen. To minimize this, slightly undercook the casserole before freezing.

Thaw overnight in the refrigerator, then bake until heated through and bubbly. The flavor remains delicious even if texture changes slightly.
