Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Butter one side of each sourdough slice and place butter-side down on a baking sheet; toast for 5 minutes until lightly golden.
  2. Step 2: In a saucepan, melt 2 tbsp butter over medium heat. Whisk in 2 tbsp all-purpose flour and cook for 1 minute, then gradually whisk in 1 cup milk until thickened (3 minutes). Remove from heat and stir in 1/2 cup grated Gruyere, 1/4 tsp salt, and 1/8 tsp white pepper until smooth.
  3. Step 3: Spread 1/4 cup Mornay sauce on each toasted bread slice (butter-side up), top with 1.5 oz sliced turkey and 0.75 oz crumbled bacon, then add another 1/4 cup Mornay sauce. Bake for 8-10 minutes until cheese is melted and bubbly.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep sourdough bread from drying out.

Can I substitute ingredients in Baked Turkey and Bacon Mornay Sandwich?
