Ingredients
Instructions
- Preheat oven to 375°F.
- Grease a 9 x 9-inch square pan.
- Mix Bisquick and water until a soft dough forms.
- Pat the dough evenly into the prepared pan.
- In a separate bowl, combine tuna, shredded Swiss cheese, chopped celery, chopped green onions, mayonnaise, Worcestershire sauce, salt, and pepper.

- Sprinkle with paprika if desired.
- Bake until edges are light brown, about 30 minutes.
Tips & Substitutions
For a creamier texture, consider adding a tablespoon of sour cream to the tuna mixture. If you don't have Swiss cheese, Gruyère or mozzarella can be good substitutes. To enhance the flavor, mix in a teaspoon of Dijon mustard or fresh herbs like dill or parsley. This recipe also lends itself well to variations, so feel free to experiment with different seafood options like crab or shrimp, similar to Hot Seafood Pie 'One-Dish' Dinner.
Serving Suggestions
Serve the tuna squares warm or at room temperature as a delightful appetizer or main dish. They pair beautifully with a fresh green salad or steamed vegetables for a complete meal. For an elevated touch, serve with a side of tartar sauce or a squeeze of lemon. These squares also make a great addition to a picnic or potluck spread, alongside other American recipes.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F for about 15-20 minutes or until heated through. You can also microwave individual portions for a quick meal, but the oven method will keep the crust crispier.
