Trust me, you’ll find yourself making it again and again, relishing the smiles of everyone around the table.

Gather these ingredients

To whip up this delightful casserole, you’ll need:

  • 1 loaf of day-old bread (French bread or challah is best, cubed): Day-old bread is golden for this dish because it’s slightly stale and absorbs the egg mixture better. Fresh bread? No worries, just give it a light toast to get it ready!

  • 1 lb breakfast sausage: Choose your favorite—pork, turkey, or even a vegetarian variety works beautifully. The sausage adds such a robust flavor to the casserole.

  • 1 medium onion, chopped: A classic base for any savory dish. The sweetness of the onion will complement the sausage perfectly.

  • 1 red bell pepper, chopped (optional): Adds a splash of color and sweetness—totally your call whether to include it!

  • 1 cup shredded cheddar cheese: Feel free to mix it up here with your favorite cheese. A sharp cheddar gives a great kick.

  • 1 cup shredded Swiss cheese: This cheese melts into gooey perfection, making each spoonful a delight.

  • 8 large eggs: The binding magic of the dish!

  • 2 cups whole milk: For a creamy, rich texture. You can substitute with any nut milk if you’re looking to keep things dairy-free.

  • ½ teaspoon dry mustard powder: This little powerhouse adds depth and a subtle zing.

  • 1 teaspoon salt: Essential for balancing flavors.

  • ½ teaspoon black pepper: A must for that gentle warmth.

  • ¼ teaspoon cayenne pepper (optional): If you’re feeling spicy, toss it in for a kick!

Preparing Ina Garten Breakfast Casserole – Make Ahead Brunch Classic

Here’s how to bring this casserole to life:

  1. Prep the bread: Cube the day-old bread. If it’s fresh, pop it into a 300°F (150°C) oven for about 10-15 minutes until it’s lightly toasted. This step is key—trust me, it makes a world of difference!

  2. Cook the sausage: In a large skillet, brown the sausage over medium heat. Drain excess grease, leaving about a tablespoon. This helps keep flavors intact without excess oil.

  3. Soften the veggies: Add the chopped onion to the skillet and sauté until softened—about 5-7 minutes. If you’re adding red bell pepper, toss it in during the last 3-4 minutes.

  4. Combine: In a large bowl, mix the cubed bread with the sausage, onion, and bell pepper. Stir in the shredded cheddar and Swiss cheese gently so everything gets well acquainted.

  5. Make the egg mixture: In a separate bowl, whisk together the eggs, milk, dry mustard powder, salt, black pepper, and optional cayenne until smooth.

  6. Finalize: Pour the egg mixture evenly over the bread and sausage mix in a greased 9×13 inch baking dish. Give everything a gentle press to ensure the bread is soaked. Cover tightly with plastic wrap and refrigerate for at least 8 hours, or preferably overnight. This is where the magic happens!

  7. Bake: Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake for 45-55 minutes until it’s set, puffed, and a lovely golden brown. Don’t skip the resting step for 10-15 minutes before serving—it makes a huge difference!

Best way to enjoy it

When it’s time to serve, this Breakfast Casserole welcomes a multitude of pairings. Think fresh fruit—berries or sliced citrus for a pop of brightness. Maybe a dollop of sour cream or a sprinkle of hot sauce for those who like a little extra zing. A side of crispy bacon or turkey sausage never hurt, either!

If you want to double-down on the brunch vibe, serve it alongside mimosas or a warm cup of coffee. Trust me; it elevates the experience!

How to store and freeze

This casserole is your best friend when it comes to leftovers! Once the dish has cooled, store any extras in an airtight container in the refrigerator. It’ll keep for 3-4 days. For optimal reheating, just pop your slice in the microwave or oven until warmed through.

Want to get ahead for the week? You can freeze portions! Wrap individual servings tightly and store them in the freezer for up to 2 months. When you’re ready to eat, just thaw in the fridge overnight and heat up.

Pro chef tips

  • If you want more flavor, consider toasting the spices in the skillet for a minute before adding the eggs. It really brings out their aroma!
  • For those who love an herbaceous touch, add fresh herbs like chives or parsley to the mix for that pop of freshness.
  • Experiment with different types of cheese; pepper jack or gouda could transform the flavor profile entirely!

Creative Twists

The great thing about this casserole is how easily it can be adjusted. Got leftover veggies? Toss ‘em in! Love spicy? Add jalapeños! You could even switch up the kind of bread—say, sourdough or brioche for a different nuance.

Your questions answered

  • Can I use fresh bread instead of day-old? Absolutely! Just make sure to toast it lightly first.
  • Can this casserole be made gluten-free? Yup! Just swap the bread for a gluten-free option—many great varieties are available.
  • What if I want to make it dairy-free? Use nut or oat milk and a dairy-free cheese substitute.
  • How long does it take to prep? About 20-30 minutes, plus the overnight chill time.
  • Can I add extra veggies? Go for it! Spinach, mushrooms, or zucchini would work fabulously.
