4-Ingredient Oven Baked Jalapeno Tuna
Servings: 4
Ingredients
2 cans (5 ounces each) jalapeno tuna, undrained
Directions
1. Preheat the oven to 375°F and lightly grease an oven-safe roasting pan if needed for easier cleanup.
2. Pour the undrained jalapeno tuna into the roasting pan and break it up gently with a fork so it spreads evenly.
3. Scatter the sliced onion over the tuna, then sprinkle the shredded cheddar cheese evenly across the top.
4. Sprinkle the crushed crackers over everything to create a simple crunchy topping.
5. Bake for 20 to 25 minutes, until the mixture is bubbling and the topping is golden. Let it rest for 5 minutes before serving.
Variations & Tips
Milder Version: If you are feeding picky eaters or anyone sensitive to spice, mix the jalapeno tuna with a little plain tuna or add extra cheese to soften the heat without changing the easy method.
Crunchier Topping: For more texture, drizzle a little melted butter over the crushed crackers before baking. That helps the topping brown more evenly and gives the casserole a richer finish.
Make It a Meal: You can spoon this baked tuna over cooked rice, toast, or baked potatoes to stretch it further for hungry family members and turn a simple pan into a more complete supper.
Pan Tip: Since the tuna goes in undrained, the mixture should stay moist as it bakes. If your pan seems especially juicy, just give it a few extra minutes in the oven so the topping can crisp and the filling can thicken a bit.
