• 1/2 teaspoon salt
• 1/2 teaspoon black pepper

Tips for the Best Results

• Let it chill so the bread soaks up the custard.
• Use day-old bread for the best texture.
• Let it rest 10 minutes before slicing.

Variations

• Swap sausage for bacon or ham.
• Add diced bell peppers or spinach.
• Use a mix of cheddar and pepper jack.

Storage
