Serving creamy tuna noodle casserole.

There is very little I find more comforting than a warm, delicious casserole for dinner. My Creamy Tuna Noodle Casserole is inspired by my mother’s recipe, with some twists of my own. However, there is one thing I couldn’t change form my mom’s classic recipe. My mom always incorporates yogurt into her casseroles for added tanginess and extra creaminess. Not only does it taste of home for me, but this easy addition also adds calcium and richness without a lot of fat and calories.

How to Make Creamy Tuna Noodle Casserole

Liz dicing an onion

Start your Creamy Tuna Noodle Casserole by dicing your onion, slicing your mushrooms, and cooking your pasta according to the package’s instructions.

Sauteing onions in pan

Then, heat some butter or olive oil in a pan and add the diced onion.

Sauteing mushrooms with onions

Sauté the onion until they start to brown, then add the mushrooms and some salt and pepper.

Adding frozen peas to pan

Once the mushrooms and onions have browned and softened, stir in the frozen peas and cook until warm. Remove from the pan and add to a large bowl.

Stirring in sauteed veggies

Add the cooked, drained pasta to the bowl and stir.

Adding tuna to bowl

Then you’ll add the canned chunk tuna to the bowl.

Adding sour cream to bowl

Next you’ll add the plain yogurt, garlic, and soy sauce.

Adding broth to bowl

Follow with the milk, and stir until everything is evenly coated.

Liz grating parmesan cheese

Finish with freshly grated parmesan cheese, and season with additional salt and pepper.

Adding tuna noodle casserole to dish

Pour the tuna mixture into a casserole dish and spread evenly.

Topping casserole with bread crumbs

Top the casserole with bread crumbs and additional grated parmesan cheese.

Drizzling casserole with olive oil

Then drizzle the whole thing with olive oil. Cover in foil, and pop it in the oven at 350 for 30-35 minutes. Remove the foil and continue baking for another 5-10 minutes until top is browned and crispy.

Easy Substitutions

  • Swap the protein: Switch out the canned tuna for canned chicken, or make it vegetarian and omit the tuna altogether and double up on the mushrooms.
  • Make it vegan: Replace the butter with olive oil, omit the tuna and add another veggie like broccoli, use soy yogurt, and your favorite plain non-dairy milk.
  • Make it gluten free: Use your favorite gluten free pasta and replace the bread crumbs with almond meal or crushed rice Chex.

Frequently Asked Questions:

What is a good side dish for tuna noodle casserole?

I like to serve it with a light salad or veggie dish, like my Syrian Salad or Roasted Provencal Vegetables.

How do you keep tuna casserole from drying out?

Don’t overcook it, keep it covered for most of the cook time, and make sure it has enough liquid so that the noodles don’t soak up all of the sauce.

How do I store leftovers?

Kept in an airtight container, leftover tuna casserole will keep in the fridge for up to 4 days.

  1. Thank you for this wonderful recipe I’ve made quite a few times for my husband’s work lunch. Another change you may consider making is swapping out the peas for shelled edamame to reduce the sugar and increase the fibre almost threefold!
