Ingredients for Tuna Casserole Recipe
• 12 oz (340 g) egg noodles (or whole wheat pasta for extra fiber)
• 2 cans (5 oz each) tuna in water, drained (wild-caught Albacore recommended)
• 1 cup frozen peas (no need to thaw—adds color and vitamin C)
• 1 small onion, finely chopped (about 1 cup; yellow or sweet onion works)
• 2 Tbsp butter (unsalted; grass-fed if you like richer flavor)
• 1 cup plain whole milk Greek yogurt (for creaminess without heaviness)
• 1 can (10.5 oz) cream of mushroom soup (low-sodium if preferred)
• ½ cup shredded sharp cheddar cheese (or a melty Colby jack blend)
• ½ cup milk (use 2% or plant-based for dairy-free tweaks)
• ½ tsp garlic powder
• ½ tsp black pepper (freshly ground if you have it)
• 1 cup crushed potato chips or breadcrumbs (for that golden baked top)
Directions for Tuna Casserole Recipe
1. Preheat your oven to 375°F (190°C).
Place a rack in the center so the topping browns evenly.
-
Cook the egg noodles in salted boiling water until just al dente (about 7 minutes).
They’ll finish cooking in the oven—avoid mushy noodles! -
While the pasta boils, melt butter in a skillet over medium heat.
Add chopped onion and sauté until soft and translucent, about 4 minutes. -
Stir in the cream of mushroom soup, milk, Greek yogurt, garlic powder, and black pepper.
Warm gently—do not boil—to keep the yogurt from splitting. -
Drain noodles and return them to the pot; fold in tuna, peas, onion mixture, and half the shredded cheese.
Use a wooden spoon to mix gently, so flakes of tuna stay intact. -
Transfer everything into a greased 9×13-inch baking dish.
Sprinkle the remaining cheese and crushed chips (or crumbs) on top for a tasty crust. -
Bake uncovered for 20–25 minutes, until bubbling at the edges and the topping is golden.
Let it rest 5–10 minutes before serving so it firms up nicely.
Tuna Casserole Recipe Servings & Timing
Makes 6 servings
Prep Time: 15 minutes
Bake Time: 25 minutes
Total Time: About 40 minutes
Variations
• Swap peas for mixed frozen veggies (corn, carrots, green beans).
• Use gluten-free pasta and dairy-free soup to suit allergies.
• Add a squeeze of lemon juice and chopped dill for brightness.
• Stir in a handful of chopped bell pepper for extra crunch.
• Mix in ½ cup cooked bacon bits for smoky flair.
Storage & Reheating
Store leftovers in an airtight container in the fridge for up to 3 days. For longer keep, freeze in portions (use freezer-safe lids) for up to 2 months. To reheat, cover with foil and bake at 350°F (175°C) for 15 minutes or microwave individual servings until hot—stir midway for even warmth. Assemble ahead and refrigerate (unbaked) up to 24 hours, then bake when you’re ready.
Notes
• Let the casserole rest before cutting—this helps the sauce set, so you avoid soupy slices.
• I learned that blending Greek yogurt with soup gives creaminess and tang without extra fat.
• If you crave more texture, stir in chopped celery or swap crumbs for crushed Ritz crackers.
FAQs
Q: Can I prepare this dish a day ahead?
A: Yes—assemble everything in the baking dish, cover tightly, and refrigerate; bake directly from the fridge, adding a few extra minutes if needed.
Q: My noodles always get mushy. What do I do?
A: Stop cooking the pasta about 2 minutes before the package recommends and drain right away—al dente noodles hold up in the oven.
Q: Is there a lower-sodium version?
A: Choose low-sodium soup, rinse the tuna well, and skip added salt—or use a pinch of sea salt at the end.
Q: Can I use fresh tuna instead of canned?
A: Canned tuna is best here for its flaky texture; fresh tuna will turn firm and steak-like when baked.
Q: How do I make this dairy-free?
A: Swap Greek yogurt for a vegan alternative, use dairy-free soup, plant-based milk, and skip the cheese or use vegan shreds.
Q: Can I double the recipe for a crowd?
A: Absolutely—just use a larger baking dish and extend baking time by 5–10 minutes until it’s bubbly.
