Step‑by‑Step Instructions for Tuna Tetrazzini

Step 1: Cook Pasta
In a large pot, bring water to a rolling boil and generously salt it. Add the spaghetti and cook according to the package instructions until it’s al dente, about 8-10 minutes. Drain the pasta and set it aside, ensuring you retain a bit of the pasta water for later use.

Step 2: Sauté Vegetables
In a deep skillet over medium heat, melt 3 tablespoons of unsalted butter. Add the finely diced red onion, sautéing until it turns soft and translucent—this should take about 3-5 minutes. Next, toss in the sliced mushrooms, stirring occasionally for another 5-6 minutes until they are golden brown and fragrant.

Step 3: Prepare Sauce
Stir in 2 cloves of minced garlic and cook for 30 seconds until aromatic. Sprinkle in 1/4 cup of all-purpose flour, whisking consistently for 1 minute to eliminate raw flour taste. Gradually pour in 2 cups of whole milk while continually whisking, cooking until the mixture thickens and is smooth, which will take about 3-4 minutes. Season with salt and pepper to taste.

Step 4: Mix Components
Gently fold in the drained tuna, broken into chunks, and the 1 cup of frozen peas into the creamy sauce. Combine the cooked spaghetti with this luscious sauce using kitchen tongs, ensuring every strand is coated in that delightful Tuna Tetrazzini mixture.

Step 5: Transfer & Bake
Preheat your oven to 350°F (175°C). Transfer the creamy tuna mixture into a greased baking dish, spreading it evenly. Sprinkle a generous layer of breadcrumbs over the top for that satisfying crunch. Bake in the oven for 15-20 minutes or until the topping is golden brown and crispy.

Step 6: Cool
Once baked to perfection, remove the Tuna Tetrazzini from the oven and allow it to cool for about 5-10 minutes. This will help the flavors meld while making it easier to serve. Enjoy your comforting creation that’s perfect for any family dinner!

Make Ahead Options

These Tuna Tetrazzini options are perfect for busy home cooks looking to save time during the week! You can prepare the creamy sauce and stir in the tuna and peas up to 24 hours ahead of time; just refrigerate it in an airtight container. Additionally, cook the spaghetti and store it separately to prevent it from getting mushy. When you’re ready to finish the dish, simply combine the sauce and pasta, transfer into a greased baking dish, top with breadcrumbs, and bake at 350°F for about 15-20 minutes until golden. This way, you’ll enjoy the same comforting flavors with minimal effort on a hectic evening!

Tuna Tetrazzini Recipe FAQs

What type of pasta is best for Tuna Tetrazzini?
I recommend using spaghetti for its perfect texture and ability to absorb the creamy sauce beautifully. However, you can experiment with other pasta shapes like fettuccine or even gluten-free options, which work just as well. Just ensure it’s cooked to al dente as it will continue to cook when baked.

How should I store leftover Tuna Tetrazzini?
Store leftover Tuna Tetrazzini in an airtight container in the fridge for up to 3-4 days. When you’re ready to enjoy it again, simply reheat in the microwave or oven until warmed through. A great tip is to sprinkle a bit of water over the top before covering it in the microwave to keep it moist!

Can I freeze Tuna Tetrazzini?
Absolutely! To freeze Tuna Tetrazzini, portion it into airtight containers or freezer bags for up to 2 months. For best results, let it cool completely before freezing. When you’re ready to eat, thaw it in the fridge overnight and then reheat in the oven at 350°F for about 20-25 minutes until fully heated through.

My sauce seems too thick—what should I do?
If your sauce turns out too thick, don’t fret! Just add a splash of milk while stirring it over low heat until it reaches your desired consistency. This will bring back that creamy texture we all love. Always start with a little and add more as necessary to prevent over-thinning.

Can I use fresh vegetables instead of frozen peas?
Yes! I often swap frozen peas for fresh ones, such as blanched green beans or spinach. If using fresh, ensure they’re cooked just until tender before mixing them into your sauce. Adding vegetables is a wonderful way to customize the dish and incorporate more nutrients!

Are there any dietary considerations for this recipe?
This Tuna Tetrazzini can be easily made gluten-free by substituting regular pasta and breadcrumbs with gluten-free alternatives. Just be sure to check your canned tuna for any allergens. If serving to pets, remember that onions and garlic can be harmful to them, so it’s best to keep those portions separate.
