How to Make Kentucky Hot Brown Casserole

When I set out to make this, I start by toasting the bread until it’s just golden and slightly crisp, creating a sturdy base for all the goodness to come. Then, I layer in that tender smoked turkey and sprinkle generous amounts of crumbled, crispy bacon and those bright cherry tomatoes.

Next comes the magical Mornay sauce – I pour it slowly over everything, watching it seep into all the nooks and crannies, knowing it’s going to create that luscious, creamy texture. As it bakes, my kitchen fills with the most incredible cheesy, savory aroma, and I can hear the gentle bubbling as the sauce heats through. When it comes out, it’s golden and irresistible, a true triumph of comfort food, similar in heartwarming spirit to my favorite turkey broccoli casserole.

Pro Tips

Always toast your bread cubes before adding them to the casserole; this step is non-negotiable for me because it prevents the bread from getting soggy and gives you that perfect textual contrast.

When selecting your turkey for this Kentucky Hot Brown Casserole, opt for a good quality smoked turkey from the deli, as it brings a depth of flavor that really elevates the whole dish.

I find that grating your own cheese for the Mornay sauce makes a huge difference; it melts much smoother than pre-shredded varieties and results in a silkier, richer sauce.

My Secret Trick: I always add a tiny pinch of freshly grated nutmeg to my Mornay sauce; it doesn’t make it taste like nutmeg, but rather enhances the savory, creamy notes in a wonderfully subtle way.

How to Store Kentucky Hot Brown Casserole

• Once cooled, cover any leftover casserole tightly with plastic wrap or transfer it to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days.
• For longer storage, you can freeze the cooked casserole. Wrap it tightly in plastic wrap, then aluminum foil, and place it in a freezer-safe bag or container. It will stay good for about 2-3 months.
• To reheat from the fridge, you can microwave individual portions or bake the whole casserole covered at 300°F (150°C) until heated through, about 20-30 minutes. If reheating from frozen, thaw overnight in the fridge, then bake as directed.

Nutritional Benefits

This heartwarming Kentucky Hot Brown Casserole isn’t just about incredible flavor; it offers some comforting nourishment too! With the smoked turkey, you’re getting a good source of lean protein, which is essential for building and repairing tissues. Plus, all that wonderful cheese in the Mornay sauce provides a healthy dose of calcium for strong bones.

FAQs

What’s the best type of bread to use for this casserole?

I find that a sturdy, thick-cut white bread or a good sourdough works best. You want something that will hold up to the creamy sauce without disintegrating, providing a lovely texture once toasted.

Can I prepare this casserole ahead of time?

Absolutely! I often assemble the entire casserole, cover it tightly, and refrigerate it overnight. Just let it come closer to room temperature for about 30 minutes before baking, adding a little extra baking time if needed.

What if I don’t have smoked turkey?

While smoked turkey adds a unique depth, you can certainly use leftover roasted turkey or even cooked chicken in a pinch. The flavor profile will shift slightly, but it will still be a delicious and comforting casserole.

Can I add vegetables to my Hot Brown Casserole?

Of course! While not traditional, I’ve had success adding finely chopped spinach or sautéed mushrooms to the layers for extra nutrition and flavor. Feel free to experiment with what you love!

Ingredients

  

For the Mornay Sauce

• 4 tbsp unsalted butter
• 4 tbsp all-purpose flour
• 2.5 cups whole milk
• 1 cup Gruyère cheese, shredded divided
• 0.5 tsp kosher salt
• 0.25 tsp black pepper freshly ground
• 1 pinch ground nutmeg

For the Casserole

• 6 slices sturdy white bread like Texas toast or brioche
• 1.5 lbs cooked turkey breast sliced or shredded
• 8 slices bacon cooked crisp and crumbled
• 2 Roma tomatoes medium, sliced
• 2 tbsp fresh parsley chopped, for garnish (optional)

Equipment

• 9x13 inch Baking Dish
• Large saucepan or Dutch oven
• Whisk

Method

 

Prepare for Baking

• Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. If your bread isn't pre-toasted, give it a quick toast or pan-fry to prevent it from getting soggy in the casserole. Cook the bacon until it's wonderfully crisp, then drain it on paper towels and crumble. Set aside.

Make the Mornay Sauce

• In a large saucepan or Dutch oven, melt the "4" tbsp of unsalted butter over medium heat. Whisk in the "4" tbsp of all-purpose flour and cook for "1" minute, stirring constantly, until it forms a pale golden roux.
• Gradually whisk in the "2.5" cups of whole milk until the mixture is smooth. Bring it to a gentle simmer, whisking frequently, and cook for "3-5" minutes until it thickens. Reduce the heat to low, then stir in "0.75" cup of the shredded Gruyère cheese until it's completely melted and smooth. Season with "0.5" tsp of kosher salt, "0.25" tsp of freshly ground black pepper, and a pinch of ground nutmeg. Remove the sauce from the heat.

Assemble the Casserole

• Arrange the "6" slices of sturdy white bread in a single layer in your prepared baking dish. Don't worry if they overlap slightly.
• Evenly distribute the "1.5" lbs of sliced or shredded cooked turkey breast over the bread. Then, pour about half of your delicious Mornay sauce evenly over the turkey layer.
• Sprinkle the crumbled "8" slices of cooked bacon over the sauce. Next, arrange the "2" sliced Roma tomatoes over the bacon.
• Pour the remaining Mornay sauce over the tomatoes, making sure to cover everything. Finally, sprinkle the remaining "0.25" cup of shredded Gruyère cheese over the top for that perfect golden crust.

Bake and Serve

• Bake for "25-30" minutes, or until the casserole is bubbly around the edges and the cheese on top is beautifully melted and lightly golden brown.
• Let the casserole rest for "5" minutes before diving in. If you're feeling fancy, garnish with "2" tbsp of chopped fresh parsley before serving.

Notes

Feel free to swap out the Gruyère for another good melting cheese like Swiss, white cheddar, or even a blend for a slightly different flavor profile.

You can assemble this casserole up to a day ahead! Just cover and refrigerate before baking. You might need to add an extra 10-15 minutes to the baking time if starting from cold.

This rich casserole is a meal in itself, but it pairs wonderfully with a crisp green salad to balance out the richness, or some roasted asparagus.

Conclusion

I genuinely hope you try this Kentucky Hot Brown Casserole! It’s truly a dish that brings smiles to faces and warmth to the soul, perfect for family dinners or a cozy evening. I promise, the rich flavors and comforting textures will make it an instant favorite, right alongside my beloved Ritz cracker chicken casserole. Enjoy every single bite, my friend!
