What Ingredients You Will Need

This comforting tuna casserole uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples that you probably already have, and if not, they’re easy to find. Plus, I’ve included a few substitution tips to make this recipe work for different diets or preferences.

• For the casserole base:
• 12 oz (340 g) egg noodles (or any short pasta you prefer)
• 2 (5 oz / 142 g) cans of tuna in water, drained (I recommend Wild Planet for best quality)
• 1 cup (240 ml) frozen peas, thawed (adds a pop of color and sweetness)
• 1/2 cup (120 ml) finely chopped onion (yellow or sweet onion works great)
• For the creamy sauce:
• 3 tbsp (45 g) unsalted butter
• 3 tbsp (24 g) all-purpose flour (or gluten-free flour blend)
• 2 cups (480 ml) whole milk (or plant-based milk like oat for dairy-free)
• 1/2 cup (120 ml) chicken or vegetable broth (adds depth of flavor)
• 1 tsp Dijon mustard (gives a subtle tang)
• 1/2 tsp garlic powder
• Salt and freshly ground black pepper to taste
• 1 cup (100 g) shredded sharp cheddar cheese (adds richness)
• 1/2 cup (50 g) shredded mozzarella cheese (for melty stretch)
• For the crispy golden topping:
• 1 cup (60 g) crushed buttery crackers (Ritz crackers recommended)
• 1/2 cup (30 g) panko breadcrumbs (for extra crunch)
• 2 tbsp (30 g) unsalted butter, melted (to bind and crisp the topping)
• 1 tbsp grated Parmesan cheese (optional, for a nutty finish)

If you want to swap things up, you can use canned salmon or shredded rotisserie chicken instead of tuna. For a dairy-free version, swap butter for olive oil and use dairy-free cheese alternatives. Frozen corn can replace peas if you’re looking for a sweeter crunch. Just remember to drain the tuna well so your casserole doesn’t get soggy!

Equipment Needed

• Large pot for boiling noodles
• Medium saucepan to make the creamy sauce
• 9×13 inch (23×33 cm) baking dish (glass or metal works fine)
• Mixing bowls for combining ingredients
• Whisk (to keep the sauce smooth)
• Measuring cups and spoons
• Colander to drain pasta
• Optional: food processor or rolling pin to crush crackers finely

I personally prefer using a non-stick saucepan for the sauce—it helps prevent scorching and makes cleanup easier. If you don’t have a baking dish that size, two smaller dishes work just as well. Using a whisk is a must-have for the sauce; trust me, lumps are the enemy here! For the topping, crushing crackers by hand is totally fine, but a food processor makes it quicker and more uniform.

Preparation Method

1. Preheat the oven to 350°F (175°C). Grease your 9×13 inch baking dish lightly with butter or non-stick spray.
2. Cook the egg noodles: Bring a large pot of salted water to a boil. Add 12 oz (340 g) egg noodles and cook according to package instructions, usually about 7-8 minutes until al dente. Drain well and set aside.
3. Prepare the creamy sauce: In a medium saucepan, melt 3 tbsp (45 g) unsalted butter over medium heat. Whisk in 3 tbsp (24 g) flour and cook for about 1-2 minutes until it turns a light golden color, stirring constantly to avoid lumps.
4. Gradually whisk in 2 cups (480 ml) whole milk and 1/2 cup (120 ml) broth. Keep whisking until the mixture thickens and bubbles, about 5 minutes.
5. Stir in 1 tsp Dijon mustard, 1/2 tsp garlic powder, salt, and pepper to taste. Reduce heat to low and add 1 cup (100 g) shredded cheddar and 1/2 cup (50 g) shredded mozzarella cheese. Stir gently until melted and smooth.
6. Combine the casserole ingredients: In a large bowl, mix the drained noodles, drained tuna, thawed peas, chopped onions, and creamy sauce. Stir gently but thoroughly to combine everything evenly.
7. Pour the mixture into the prepared baking dish, spreading it out evenly.
8. Make the crispy topping: In a small bowl, combine 1 cup (60 g) crushed buttery crackers, 1/2 cup (30 g) panko breadcrumbs, 2 tbsp (30 g) melted butter, and 1 tbsp Parmesan cheese if using. Mix until the crumbs are evenly coated.
9. Sprinkle the topping evenly over the casserole.
10. Bake the casserole: Place the dish in the preheated oven and bake for 25-30 minutes, or until the topping is golden brown and crispy, and the casserole is bubbling around the edges.
11. Let it rest for 5 minutes before serving. This helps the flavors settle and makes it easier to scoop out.

Pro tip: If your topping starts to brown too quickly, tent the casserole loosely with foil halfway through baking. And when stirring the sauce, patience is key—rushing can lead to lumps, and nobody wants that.

Cooking Tips & Techniques

For the best comforting tuna casserole, a few tips from my kitchen to yours:

• Drain the tuna well: Excess moisture can make the casserole soggy. I like to press the drained tuna gently between paper towels.
• Cook pasta al dente: It’ll continue cooking in the oven, so don’t overdo it in the boiling water.
• Use room temperature milk: It blends better into the roux (flour and butter mixture) and helps prevent lumps.
• Whisk constantly: When making the sauce, keep the whisk moving to get a silky smooth béchamel base.
• For topping crunch: The mix of panko and crushed crackers is my secret weapon—panko brings the crunch, crackers add buttery flavor.
• Don’t skip the rest time: Letting the casserole rest after baking makes it easier to serve and lets flavors marry beautifully.

I once accidentally forgot to add the mustard, and honestly, the sauce tasted flat. That little tang really wakes up the casserole. Also, I learned the hard way that using fresh onions instead of dried makes a noticeable difference in flavor and texture.

Variations & Adaptations

This comforting tuna casserole recipe is incredibly versatile. Here are some ways I’ve tweaked it for different tastes and needs:

• Gluten-Free: Swap the all-purpose flour for a gluten-free blend and use gluten-free pasta. Make sure your breadcrumbs and crackers are gluten-free too.
• Low-Carb: Use spiralized zucchini or cauliflower rice instead of noodles. The creamy sauce still works beautifully here.
• Vegetarian: Replace tuna with cooked chickpeas or shredded jackfruit for that meaty texture, and use vegetable broth.
• Extra Veggies: Add sliced mushrooms, diced bell peppers, or spinach to the mix for a veggie boost.
• Spicy Kick: Stir in a pinch of red pepper flakes or a dash of hot sauce into the sauce for a little heat.

One version I love is swapping tuna for canned salmon, which adds a richer flavor. I also sometimes add a handful of grated carrot for sweetness and texture. You can adjust cheese types, too—try pepper jack for some zing or Swiss for nuttiness.

Serving & Storage Suggestions

This tuna casserole is best served hot, straight from the oven, when the topping is still crispy and the cheesy sauce is bubbling. It pairs wonderfully with a simple green salad or steamed green beans for a balanced meal. A crisp white wine or a light iced tea also complements the richness nicely.

If you have leftovers (which might be rare!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F (175°C) oven for about 15 minutes, or microwave in shorter intervals to keep the topping from getting soggy.

Freezing is possible but keep in mind the topping might lose some crunch. Freeze the casserole before baking for best results, thaw overnight in the fridge, then bake as usual.

Flavors tend to deepen after sitting for a day, so this casserole can actually taste better the next day—if it lasts that long!

Nutritional Information & Benefits

How do I keep the topping crispy after baking?

Serve immediately after baking for best crunch. If reheating, use the oven instead of microwave and keep the casserole uncovered.

Can I prepare this casserole ahead of time?

Yes! Assemble it, cover, and refrigerate for up to 24 hours before baking. You may need to add a few extra minutes to the bake time.

Is there a dairy-free version of this recipe?
