Why This Thanksgiving Leftover Breakfast Casserole Is a Must-Try

Thanksgiving dinner is legendary for its abundance, and while we cherish every bite, the sheer volume of leftovers can sometimes feel overwhelming. This breakfast casserole offers an elegant and incredibly simple solution. It’s a fantastic way to give new life to your holiday staples, preventing food waste while creating a dish that feels entirely new and exciting. Imagine waking up to the enticing scent of warm, savory, and slightly sweet goodness, without having to spend hours in the kitchen.

The Star Ingredients: A Symphony of Holiday Flavors

  • King’s Hawaiian Rolls: These sweet, fluffy rolls are the secret weapon of this casserole. When cubed and baked, they soak up the rich egg custard, becoming incredibly tender and adding a delightful hint of sweetness that perfectly balances the savory elements. They create a unique, irresistible texture that sets this casserole apart from traditional bread puddings.
  • Leftover Turkey: Diced turkey meat transforms from a dinner centerpiece into a flavorful breakfast protein. Whether it’s white meat, dark meat, or a mix, the turkey adds substance and that unmistakable holiday essence to every forkful.
  • Thanksgiving Vegetables: This is where you can truly customize. Have leftover roasted sweet potatoes? Perfect. Brussels sprouts? Excellent. Green beans? Absolutely! Even a mix of these will work wonderfully. These veggies add color, nutrients, and varying textures, making each bite interesting.
  • Aromatic Herbs: The lingering flavors of Thanksgiving often come from the herbs used in cooking. Sage, thyme, parsley, and rosemary from your holiday preparations are ideal for infusing this casserole with that comforting, familiar warmth. They tie all the ingredients back to the holiday meal, making it truly a “Thanksgiving” breakfast.
  • Eggs and Milk: The classic custard base that binds everything together. It ensures a moist, tender casserole that’s both satisfying and light.

Beyond the Basics: Customization and Serving Suggestions

One of the best aspects of this Thanksgiving Leftover Breakfast Casserole is its versatility. Don’t be afraid to experiment with what you have on hand!

  • Add Cheese: A sprinkle of shredded cheddar, Gruyere, or even a Monterey Jack blend would add a wonderful melty, savory layer to the casserole. Add it during the last 15-20 minutes of baking for a golden, bubbly top.
  • Spice It Up: If you enjoy a bit of a kick, a pinch of red pepper flakes or a dash of hot sauce in the egg mixture could provide a welcome zing.
  • Different Veggies: Beyond the suggested sweet potatoes, Brussels sprouts, or green beans, consider leftover roasted carrots, parsnips, or even a bit of corn for extra flavor and texture.
  • Optional Toppings: While cranberry relish or gravy are classic accompaniments, you could also serve this casserole with a dollop of sour cream, a sprinkle of fresh chives, or even a drizzle of maple syrup for a sweet and savory contrast.

This casserole is incredibly satisfying on its own, but it pairs beautifully with a fresh fruit salad or a steaming cup of coffee. It’s ideal for a leisurely weekend breakfast, a festive brunch gathering, or even a simple, hearty weeknight meal when you’re craving some holiday comfort.

Thanksgiving Leftover Breakfast Casserole

Thanksgiving leftovers are turned into a delicious breakfast casserole filled with Hawaiian rolls, turkey, veggies and herbs!
Servings: 8 people
Prep Time: 15 minutes
Cook Time: 1 hour
Total Time: 1 hour 15 minutes
Author: Whitney Bond
Course: Breakfast, Brunch
Cuisine: American

Ingredients

  • 12 King’s Hawaiian Rolls , cubed
  • 2 cups leftover cooked turkey, diced
  • 2 cups leftover veggies, such as sweet potatoes, Brussels sprouts or green beans
  • 6 large eggs
  • 2 cups milk
  • 1 tsp kosher salt
  • ¼ tsp black pepper
  • 2 tsp leftover Thanksgiving herbs, a combination of sage, thyme, parsley, and/or rosemary
  • ½ cup leftover cranberry relish or gravy

Instructions

  • Preheat your oven to 350°F (175°C).
  • In a large casserole dish (9×13 inch works well), gently combine the cubed Hawaiian rolls, diced leftover turkey, and your choice of leftover veggies. Ensure they are evenly distributed.
  • In a separate large mixing bowl, whisk the eggs until well beaten. Then, add the milk, kosher salt, black pepper, and your blend of Thanksgiving herbs. Continue whisking until all ingredients are thoroughly combined, creating a smooth custard mixture.
  • Carefully pour the egg and milk mixture over the ingredients in the casserole dish. Gently toss or press down lightly to ensure the Hawaiian rolls and other ingredients are fully saturated with the liquid. This helps create that delightful custardy texture.
  • Bake the casserole uncovered for the first 30 minutes. After 30 minutes, cover the dish tightly with aluminum foil and continue to bake for another 30 minutes. This two-stage baking helps the casserole cook through evenly and prevents the top from browning too quickly.
  • Once baked, let the casserole rest for a few minutes before serving. Serve warm with a generous dollop of leftover cranberry relish or a drizzle of gravy on the side.

This effortless approach to turning Thanksgiving leftovers into something new and exciting is truly a game-changer. The casserole is substantial enough to keep you satisfied, yet the light, sweet Hawaiian rolls prevent it from feeling overly heavy, making it perfect for any time of day. The combination of sweet and savory notes, enhanced by the familiar holiday herbs, creates a flavor profile that is both nostalgic and refreshingly innovative.

Tips for Success & Storage

  • Don’t Overmix: When combining the ingredients in the casserole dish and pouring the egg mixture, be gentle. You want to coat everything without mushing the rolls or turkey too much.
  • Even Saturation: Ensure the cubed Hawaiian rolls are well-coated with the egg mixture. This is key for them to puff up and become wonderfully soft during baking.
  • Make Ahead: This casserole is fantastic for meal prep! You can assemble it the night before, cover it tightly, and refrigerate. Just remember to add about 15-20 minutes to the baking time if baking from cold.
  • Storage: Leftover casserole can be stored in an airtight container in the refrigerator for 3-4 days.
  • Reheating: Individual portions can be reheated in the microwave, or you can warm larger portions in the oven at 300°F (150°C) until heated through.

For those who love a good Thanksgiving leftover creation, this breakfast casserole stands out as an ingenious way to savor those cherished holiday flavors in a completely new light. It’s warm, hearty, and imbued with the spirit of the season, making it ideal for fueling your Black Friday shopping spree or a relaxed weekend at home. It truly is the gift that keeps on giving!

Personally, I am a huge fan of cranberry relish, and it pairs perfectly with this savory-sweet casserole. I often use a homemade Cranberry Jalapeno Relish leftover from my oven-roasted turkey. The tartness and slight spice of the relish cut through the richness of the casserole, creating a truly memorable breakfast experience. Don’t underestimate the power of a good condiment to elevate your dish!
