Measuring Spoons
Accurate measuring spoons guarantee the right balance of mustard, mayonnaise, and tarragon, enhancing the sandwich’s flavor without overpowering it.
Spatula
A sturdy spatula is key for flipping the sandwich gently, preserving its golden crust and gooey interior without breaking it apart.
Cutting Board
A reliable cutting board provides a stable surface to assemble and slice the sandwich cleanly, making serving neat and easy.
Turkey and Swiss Sandwich
Equipment
- 1 Nonstick Skillet
- 1 Spreader or Butter Knife
- Measuring Spoons (1/2 tsp, 1 tbsp sizes recommended)
- 1 Spatula
- 1 Cutting board
Ingredients
- 1 ½ tablespoons Dijon mustard
- 1 ½ tablespoons fat-free mayonnaise
- ½ teaspoon dried tarragon leaves
- 8 slices sourdough bread
- 8 ounces oven-roasted turkey breast thinly sliced (preferably from deli)
- 8 slices Swiss cheese
- 2 tablespoons unsalted butter
Instructions
- Prepare the Flavorful Spread: In a small mixing bowl, whisk together the Dijon mustard, fat-free mayonnaise, and dried tarragon leaves until well combined. This zesty spread will add a bright, herby layer of flavor to the sandwich.
- Assemble the Sandwich Layers: Lay out four slices of sourdough bread on a clean surface. Evenly spread the mustard mixture on one side of each slice.On top of the spread, layer two slices of Swiss cheese and a generous portion of the oven-roasted turkey breast. Then cover each with the remaining slices of bread, spread side down, creating four sandwiches.
- Heat the Skillet and Melt Butter: Place a nonstick skillet over medium heat and add the butter. Allow it to melt completely and start to bubble slightly—this will ensure a crispy, golden exterior on the bread.
- Cook the Sandwiches to Perfection: Carefully transfer two sandwiches at a time to the skillet. Cook for about 3 minutes on the first side, pressing gently with a spatula to help the cheese melt evenly. Flip the sandwiches and cook for an additional 3 minutes or until the bread is golden brown and the cheese is melted through.
- Serve Warm and Enjoy: Remove the sandwiches from the skillet and let them rest for a minute before slicing. Serve immediately to enjoy the warm, melty cheese and savory turkey with every bite.
Notes
- For a richer flavor, consider using whole butter instead of unsalted.
- If you prefer a different cheese, Gruyère or provolone make excellent substitutes.
- To reduce sodium, opt for low-sodium turkey breast and Swiss cheese varieties.
- This sandwich is best enjoyed fresh but can be wrapped and refrigerated for up to 24 hours; reheat in a skillet or toaster oven for best results.
- Adding fresh spinach or tomato slices inside the sandwich before grilling can add a refreshing twist.
Chef’s Insider Tips For Excellence
To achieve the perfect Grilled Turkey & Swiss Sandwich, start by using quality sourdough bread — its sturdy texture crisps beautifully while holding up to the fillings without becoming soggy.
Spreading the mustard-mayo-tarragon mixture evenly on each bread slice ensures every bite bursts with flavor, so don’t rush this step.
When cooking, medium heat is key; too high can burn the bread before the cheese melts, and too low will dry out the sandwich. Pressing gently with a spatula while grilling encourages even melting of the Swiss cheese and helps seal the sandwich for a satisfying crust.
For an extra touch, try adding a light sprinkle of black pepper or swapping tarragon with fresh herbs like thyme or basil to experiment with flavors.
Lastly, using butter instead of oil imparts a richer taste and golden finish that’s hard to beat.
Creative Serving Suggestions To Impress
This sandwich shines on its own but pairs beautifully with a variety of sides.
A crisp green salad tossed in lemon vinaigrette complements the rich cheese and turkey with refreshing acidity.
For heartier meals, serve alongside baked sweet potato fries or a cup of tomato basil soup to create a comforting classic combo.
If you’re hosting, cut sandwiches into halves or quarters and arrange on a platter with pickles and olives for an inviting appetizer board.
Adding sliced avocado or roasted red peppers inside the sandwich adds creaminess and depth.
Don’t forget a cold glass of iced tea or sparkling water with lemon for a complete, satisfying meal experience.
Smart Storage And Reheating Tips
If you have leftovers, wrap each sandwich tightly in plastic wrap or foil and store in the refrigerator for up to 24 hours.
To reheat without losing crispiness, avoid the microwave; instead, warm the sandwich in a skillet over low heat or use a toaster oven until the cheese melts and bread crisps again.
If preparing ahead for meal prep, assemble sandwiches but hold off on grilling until mealtime to maintain freshness.
For longer storage, sandwiches can be frozen wrapped tightly in foil and stored in a freezer-safe bag for up to one month.
Thaw overnight in the fridge before reheating to keep texture and flavor intact.
Common Questions About Recipe
1. Can I use other types of bread
Absolutely! While sourdough is ideal for its texture and flavor, whole wheat, multigrain, or rye bread also work well, just watch the grilling time as some breads toast faster.
2. What if I don’t have dried tarragon
You can substitute with other herbs like dried basil, thyme, or even a pinch of Italian seasoning to maintain that herby note.
3. Is it possible to make this sandwich dairy-free
Yes, try using dairy-free cheese slices and swap butter for olive oil or a plant-based spread. The flavor will be slightly different but still delicious.
4. How do I prevent the sandwich from becoming soggy
Be sure to toast the bread just until golden on medium heat and avoid overloading with moist ingredients. Spreading the mustard-mayo mixture on the bread helps create a moisture barrier.
5. Can I add vegetables inside the sandwich
Definitely! Thin slices of tomato, spinach, or roasted peppers make great additions without compromising texture or taste.
