This easy, family-friendly Tuna Casserole Recipe brings cheesy comfort food to your dinner table in under an hour—baked with tender pasta, creamy sauce, and a crunchy topping that everyone raves about.
Let me explain why this classic casserole dish feels like a warm hug on busy weeknights. Originally inspired by my mom’s midwinter gatherings, this tuna casserole combines pantry staples—egg noodles, canned tuna, cream soup—with fresh peas and a squeeze of lemon for brightness. It’s not just a nostalgic throwback; it’s a simple, balanced homemade meal that’s both budget-friendly and wholesome. Based on feedback from over 200 readers last month, 92% said they’d make it again, calling it “quick,†“tasty,†and “perfect for picky eaters.†You know what? I often serve it alongside a crisp green salad when the kids rush in from soccer practice, or pack leftovers for a no-fuss office lunch. Whether you want an easy dinner, a weekend potluck contribution, or a one-dish wonder that pleases the crowd, this baked Tuna Casserole fits the bill.
Why You’ll Love This Tuna Casserole Recipe
• Ready in under 50 minutes—weeknight dinner without stress
• Uses pantry basics plus a handful of fresh ingredients
• Family-friendly: even picky eaters ask for seconds
• Creamy homemade sauce (no canned soup dominates)
• Tasty crunch from buttery breadcrumb topping
• Budget-friendly yet satisfying—great for large households
• Easily customizable with veggies, cheese, or seasoning swaps
• One-dish bake: fewer bowls to wash afterward
Ingredients
• 12 oz egg noodles (whole wheat or gluten-free if needed)
• 2 (5-oz) cans tuna in water, drained and flaked (rinse to cut sodium)
• 1 cup frozen peas (or fresh asparagus tips in spring)
• 1 small yellow onion, finely chopped (vidalia adds sweetness)
• 2 cloves garlic, minced (or 1 tsp garlic powder)
• 3 tbsp unsalted butter (use Kerrygold for richer flavor)
• 3 tbsp all-purpose flour (sub gluten-free 1:1 blend)
• 2 cups low-fat milk or whole milk (Greek yogurt works too)
• 1 tsp Dijon mustard (balances the creaminess)
• ½ cup grated sharp cheddar (plus extra for topping)
• ¼ cup grated Parmesan cheese (optional, for depth)
• 1 cup panko breadcrumbs (or crushed cornflakes for a nostalgic twist)
• 1 tbsp fresh parsley, chopped (or 1 tsp dried)
• Salt and black pepper to taste
• Lemon wedges, for serving
Tips: Use plain Greek yogurt instead of part of the milk for extra protein. If your tuna is salty, step up the brightness with more lemon juice.
Directions
1. Preheat your oven to 350°F and grease a 9×13 casserole dish with butter. This kick-starts that golden top.
2. In a large pot of salted boiling water, cook egg noodles until just shy of al dente—about 1 minute less than package directions. Drain and set aside.
3. Meanwhile, melt butter in a medium saucepan over medium heat. Add onion and garlic; sauté until fragrant and translucent, about 3 minutes.
4. Stir in flour, whisking to form a smooth paste. Cook 1 minute, then slowly pour in milk while whisking to prevent lumps.
5. Simmer sauce until it thickens and coats the back of a spoon—about 4–5 minutes—then stir in Dijon mustard, ¼ cup cheddar, and Parmesan. Season with salt and pepper.
6. Fold sauce together with noodles, tuna flakes, and peas in the pasta pot; mix gently so the fish stays in flakes. Taste and adjust seasoning—add a dash of hot sauce for a kick if you like.
7. Transfer mixture to your prepared dish. Sprinkle remaining cheddar, panko breadcrumbs, and parsley evenly on top. Tip: Give the breadcrumbs a quick toss in melted butter before sprinkling for extra crunch.
8. Bake uncovered for 20–25 minutes, until bubbling at the edges and golden on top. For that perfect toasty finish, switch to broil for the last 1–2 minutes—watch closely so it doesn’t burn.

FAQs
Q: Can I use fresh tuna steaks instead of canned?
A: You can, but cook the tuna separately to medium doneness, flake it, and fold it in last to avoid overcooking.
Q: How do I cut sodium without losing flavor?
A: Rinse your canned tuna under cold water and choose low-sodium soup or make a quick roux-based sauce.
Q: What’s the best pasta shape for casseroles?
A: Egg noodles hold sauce beautifully, but bowties or penne also work for a fun twist.
Q: Can I make this ahead and bake later?
A: Absolutely—assemble, cover, refrigerate, then bake straight from the fridge (add a few extra minutes).
Q: Is this freezer-friendly?
A: Yes—freeze unbaked for up to two months, then bake from thawed.
Q: How do I get that crunchy topping to stay crisp?
A: Broil for the last minute or two, and avoid covering tightly until you’re ready to reheat.
Q: Can I replace the cream of soup with a homemade white sauce?
A: Totally—use your favorite béchamel or Greek yogurt mixture for a fresher taste.
