What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, which is always a win when you want comfort food fast.

• Egg Noodles: About 8 ounces (225 grams), cooked al dente. I prefer wide egg noodles for that perfect bite.
• Canned Tuna: Two 5-ounce (140 grams) cans, drained. Chunk light tuna works great, but you can use albacore if you like it meatier.
• Sour Cream: 1 cup (240 ml). Adds that creamy tang and richness.
• Cheddar Cheese: 1 ½ cups (150 grams), shredded. Sharp cheddar gives a nice flavor kick.
• Frozen Peas: 1 cup (150 grams), thawed. Adds a pop of color and sweetness.
• Onion: ½ small yellow onion, finely chopped. For a subtle savory note.
• Garlic: 2 cloves, minced. Because garlic always makes everything better.
• Mayonnaise: ½ cup (120 ml). Helps bind the casserole and adds moisture.
• Milk: ½ cup (120 ml), whole or 2%. Keeps the sauce smooth.
• Worcestershire Sauce: 1 teaspoon. Adds a subtle umami depth.
• Potato Chips: 2 cups (about 60 grams), crushed. Classic salted or kettle-cooked chips work best for that extra crunch.
• Salt and Pepper: To taste. Essential for balancing flavors.
• Butter: 1 tablespoon (14 grams), melted. Drizzled over chips for extra crispiness.

Pro tip: I recommend using a trusted brand of potato chips like Lay’s or Kettle Brand for the topping—they hold up nicely during baking without getting soggy. Also, if you want to swap out peas for green beans or corn depending on what’s in season, go for it! This recipe is forgiving and flexible.

Equipment Needed

• Large Pot: For boiling the egg noodles. A heavy-bottomed pot helps prevent sticking.
• Colander: To drain the noodles and tuna.
• Mixing Bowls: One large for tossing everything together, and a smaller one for crushing the potato chips.
• Sharp Knife and Cutting Board: For prepping onion and garlic.
• 9×13 Inch Baking Dish: This size fits the casserole perfectly for even cooking.
• Measuring Cups and Spoons: Accuracy is key for the sauce’s balance.
• Spatula or Large Spoon: For mixing and spreading the casserole evenly.

If you don’t have a casserole dish, a similar oven-safe baking pan will work fine. For crushing the potato chips, I’ve often used the bottom of a sturdy glass—budget-friendly and effective! Also, a cheese grater with larger holes helps shred cheddar quickly, especially when you’re in a hurry.

Preparation Method

1. Preheat your oven to 350°F (175°C). This sets the stage while you prep your ingredients.
2. Cook the egg noodles: Bring a large pot of salted water to a boil. Add 8 ounces (225 grams) of egg noodles and cook for about 7 minutes until al dente. Drain and set aside.
3. Sauté the aromatics: In a small pan over medium heat, melt a teaspoon of butter or oil. Add ½ finely chopped onion and 2 minced garlic cloves. Cook until softened and fragrant, about 3 minutes. Remove from heat.
4. Mix the casserole filling: In a large bowl, combine the cooked noodles, drained tuna (2 cans, 140g each), sautéed onion and garlic, 1 cup (150g) shredded cheddar cheese, 1 cup (240ml) sour cream, ½ cup (120ml) mayonnaise, ½ cup (120ml) milk, 1 cup (150g) thawed peas, and 1 teaspoon Worcestershire sauce. Stir gently to mix. Season with salt and pepper to taste.
5. Transfer the mixture to a greased 9×13 inch (23×33 cm) baking dish. Spread it out evenly with a spatula.
6. Prepare the potato chip topping: Place 2 cups (60g) of potato chips in a small bowl and crush them lightly with your hands or the bottom of a glass—leave some chunks for texture. Drizzle 1 tablespoon (14g) melted butter over the chips and toss to coat.
7. Sprinkle the crushed potato chips evenly over the casserole. This will give you that signature crispy, salty crust.
8. Bake for 25-30 minutes: The casserole should be bubbly around the edges and the potato chips golden brown and crisp. If the chips start browning too quickly, cover loosely with foil.
9. Rest before serving: Let the casserole cool for about 5 minutes—it helps the sauce thicken and makes serving easier.

Pro tip: If you notice the sauce looks too thick before baking, add a splash more milk. Also, stirring the casserole halfway through baking isn’t necessary and can break up the crispy topping, so resist the urge!

Cooking Tips & Techniques

Let’s face it, casseroles can sometimes turn out soggy or bland if you’re not careful. Here are some tips I’ve picked up after a few trial runs:

• Don’t overcook the noodles: They’ll finish cooking in the oven, so undercooking slightly keeps the texture just right.
• Drain tuna well: Excess moisture can make your casserole watery. Press the tuna gently in a colander or use paper towels.
• Use sharp cheddar: It melts beautifully and adds a tangy punch that balances the creamy sauce.
• Crush potato chips just enough: Too fine and you lose that crunch; too chunky and they might not stick well. Aim for bite-sized pieces.
• Butter the chips: This little trick helps them brown nicely without burning.
• Timing is key: Prep ingredients while the noodles cook to save time. Multitasking is your friend!
• Let it rest: I can’t stress enough how this step helps the casserole set up and makes serving cleaner.

One time, I got impatient and served it straight from the oven—let’s just say it was tasty but messy! Patience pays off here.

Variations & Adaptations

This crispy tuna casserole with potato chips recipe is super flexible. Here are a few ideas to switch things up:

• Dietary swaps: Use gluten-free egg noodles and check your potato chips are GF to make this allergy-friendly.
• Vegetable twists: Swap peas for corn, chopped green beans, or even diced mushrooms for different textures and flavors.
• Cheese alternatives: Try pepper jack or smoked gouda for a flavor twist.
• Cooking method: If you’re short on oven space, you can bake individual portions in ramekins or use an air fryer at 320°F (160°C) for about 15 minutes (watch closely!).
• Personal favorite variation: I once added a teaspoon of Dijon mustard to the sauce for a subtle tang that really lifted the whole dish—highly recommend!

Feel free to tailor the recipe to your taste buds and pantry. It’s all about making this classic your own.

Serving & Storage Suggestions

Serve this casserole warm, straight from the oven, ideally with a simple side salad or some steamed green veggies to balance the richness. A crisp white wine or a cold glass of iced tea pairs nicely.

Leftovers? Store them in an airtight container in the fridge for up to 3 days. When reheating, cover loosely with foil and warm at 325°F (160°C) for about 15 minutes to revive that crispy potato topping. Or microwave on medium power until heated through, then briefly broil to crisp up the chips.

The flavors actually deepen after a day or two, so this casserole is perfect for making ahead. Just be prepared for the potato chips to soften over time—adding fresh chips on top before reheating can bring back the crunch.

Nutritional Information & Benefits

FAQs About Crispy Tuna Casserole with Potato Chips

Can I use fresh tuna instead of canned?

Fresh tuna isn’t ideal for this casserole since canned tuna is already cooked and has the right texture. Using fresh would require cooking it separately and might alter the dish’s moisture balance.

What if I don’t have egg noodles?

Any short pasta like macaroni, rotini, or penne can work well. Just adjust cooking times accordingly.

How do I keep the potato chips from getting soggy?

Crush them just before baking and drizzle melted butter over them. Bake uncovered and avoid stirring the chips into the casserole.

Can I prepare this casserole ahead of time?

Yes! Assemble it, cover tightly, and refrigerate for up to 24 hours before baking. Add the potato chip topping right before baking for best results.

Is there a dairy-free version?

Swap sour cream and mayonnaise for dairy-free alternatives, use dairy-free cheese, and check that your potato chips don’t contain dairy ingredients. It won’t be quite the same but still tasty!
