Chicken Cordon Bleu Sandwich Ingredients
For the Chicken
• Chicken Breast Tenderloins – Primary protein source, providing richness and flavor; substitute with chicken thighs for a juicier option.
• Cold Water – Used for marinating the chicken, keeping it tender; essential for marinade.
• Lemon Juice Concentrate – Adds acidity for flavor balance; fresh lemon juice can be used interchangeably.
• Egg – Binds the coating, ensuring it adheres well; consider flax eggs for a vegan alternative.
• Whole Milk – Enhances richness in the egg bath; unsweetened almond milk can serve as a dairy-free substitute.
• Flour – Creates the coating for the chicken, providing crispy texture; gluten-free flour blends work well for sensitivity.
• Powdered Sugar and Spices (Paprika, Salt, Pepper, etc.) – Season the flour for the breading; customize spices according to taste preferences.
• Peanut or Canola Oil – Required for frying, providing moisture and crispness; can substitute with vegetable oil or ghee.

• Butter (Maple Wood Smoked if available) – For toasting the buns, adding flavor; any type of butter or margarine can be used.
For the Maple Mustard Sauce
• Mayonnaise – Forms the base of the maple mustard sauce; Greek yogurt can act as a lower-fat substitute.
• Maple Syrup – Sweetness component in the sauce, enhancing flavor; honey can be a good alternative.

Step‑by‑Step Instructions for Chicken Cordon Bleu Sandwiches
Step 1: Marinate the Chicken
In a ziplock bag, combine chicken breast tenderloins with cold water and lemon juice concentrate, ensuring the chicken is fully submerged. Seal the bag and refrigerate for at least 30 minutes to let the flavors infuse and keep the chicken tender while you prepare the remaining ingredients for the Chicken Cordon Bleu Sandwiches.
Step 2: Prepare the Maple Mustard Sauce
In a small mixing bowl, combine mayonnaise, maple syrup, and whole grain mustard until smooth. Taste and adjust the sweetness or tanginess to your liking. Once combined, cover the bowl with plastic wrap and refrigerate, allowing the flavors to meld while you move on to breading the chicken.
Step 3: Make the Seasoned Flour
In a large ziplock bag, whisk together flour, powdered sugar, paprika, salt, and pepper until well combined. Seal the bag and shake thoroughly to distribute the seasoning evenly. This seasoned flour will create a crispy coating for the Chicken Cordon Bleu Sandwiches once the chicken is ready to fry.
Step 4: Prepare the Egg Wash
In a medium bowl, whisk together the egg and whole milk until well blended. This egg wash will help the seasoned flour adhere to the marinated chicken, ensuring a deliciously crispy exterior. Set this mixture aside as you’re ready to bread the chicken pieces next.
Step 5: Bread the Chicken
Remove the chicken from the marinade, allowing any excess liquid to drip off. Dip each piece into the seasoned flour, ensuring it’s fully coated, then into the egg wash, and finally back into the flour for a second coating. This double-dipping technique will guarantee a flavorful and crispy texture for your Chicken Cordon Bleu Sandwiches.
Step 6: Fry the Chicken
In a large frying pan, heat peanut or canola oil over medium-high heat until it reaches 350°F (175°C), or until a breadcrumb dropped in sizzles. Carefully fry the breaded chicken pieces in batches, cooking each side for about 5-6 minutes or until golden brown and cooked through. Once done, transfer them to a paper towel-lined plate to drain excess oil.
Step 7: Toast the Buns
While the chicken is frying, preheat your broiler. Spread butter on the cut sides of the hamburger buns and place them under the broiler for 1-2 minutes, or until golden and slightly crisp. Keep a close eye on them to prevent burning, as this adds a delightful buttery flavor to your Chicken Cordon Bleu Sandwiches.
Step 8: Broil the Ham and Cheese
On a baking sheet, layer the thinly sliced boiled ham and top with shredded Swiss cheese. Place the sheet under the broiler for about 2-3 minutes, until the cheese melts and bubbles. This step brings melty goodness to your sandwich, perfectly complementing the crispy chicken.
Step 9: Assemble the Sandwiches
To assemble your Chicken Cordon Bleu Sandwiches, start by placing a piece of fried chicken on the bottom half of each toasted bun. Add a generous layer of the broiled ham and melted cheese, then drizzle with the chilled maple mustard sauce. Finally, cap them with the top of the bun and serve immediately for a warm, comforting meal!

Make Ahead Options
These Chicken Cordon Bleu Sandwiches are perfect for busy weeknights and make ahead meal prep! You can marinate the chicken tenderloins in the cold water and lemon juice for up to 24 hours in advance. Additionally, prepare the maple mustard sauce and keep it in the refrigerator for up to 3 days. For the best results, bread the chicken just before frying to retain its crispy texture. When you’re ready to serve, simply fry the chicken, toast the buns, and assemble the sandwiches with the broiled ham and melted cheese. This efficient prep ensures that every bite is just as delicious and satisfying, saving you time and effort!

Tips for the Best Chicken Cordon Bleu Sandwiches
Keep Chicken Tender: Marinate for at least 30 minutes to ensure your chicken stays juicy and flavorful. Avoid marinating too long as it can break down the texture.
Perfectly Crispy Coating: Double-dip the chicken in the seasoned flour for an extra crunch. Ensure the oil is hot enough to maintain the crispy texture during frying.
Customize Your Sauce: Adjust the maple syrup and mustard to personalize the sweetness and tang of your maple mustard sauce. This enhances the flavor of your Chicken Cordon Bleu Sandwiches.
Don’t Rush the Frying: Fry in batches and avoid overcrowding the pan. This helps maintain the oil’s temperature, ensuring each piece cooks evenly without becoming greasy.
Serve Immediately: Enjoy your sandwiches fresh! Assembling right before serving keeps the buns crispy and the cheese gooey, making every bite delightful.
