Ingredients

• 3 (5 oz) cans tuna in olive oil
• ¼ cup sour cream
• ¼ cup mayo
• ½ tsp lemon pepper seasoning
• 8 oz sliced swiss cheese
• 1 tsp garlic powder

• 2 (8 oz) French bread loaves

Directions

1. Line two cookie sheets with aluminum foil.
2. Set top rack in the second position of the oven and start the broiler on high.
3. Slice French bread in half lengthwise. Place tops on one cookie sheet and bottoms on the other with cut side facing up.
4. Brush the cut side of the top loaves with olive oil.
5. In a medium sized bowl break up drained tuna.
6. Stir in sour cream, mayo and seasonings.
7. Portion mixture between the two bottom loaves.
8. Cover bottom loaves with swiss cheese slices.
9. Broil top loaves for 2 minutes. (keep watching)
10. Broil bottom loaves for 4 minutes (still keep watching)
11. Place the tops back on the bottom loaves and slice into servings.

You can add whatever toppings suit you.

Notes

• Never walk away: The broiler works fast—watch the loaves the whole time so they toast, not burn.
• Rack position: The second rack from the top keeps the bread close enough to brown without scorching.
• Brush for crunch: The olive oil on the cut tops is what gives them that crisp, golden edge.
• Toast separately: Tops go 2 minutes, cheese-topped bottoms go about 4—they need different times to melt and crisp.
• Toppings: Add lettuce, tomato, or onion after broiling so they stay fresh.

Why This Works

• Broiler heat toasts fast: Direct top-down heat crisps the French bread in minutes, giving the sandwich its signature crunch.
• Oil conducts heat: Brushing the cut side with olive oil helps the surface crisp and brown evenly.
• Swiss melts and binds: The cheese softens over the tuna and glues the filling to the bread as it sets.
• Creamy, zesty filling: Sour cream and mayo keep the tuna moist while the seasonings add tang against the mild Swiss.
