This delicious, creamy tuna casserole is made with baby bella mushrooms, parmesan cheese, and tangy yogurt.
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
Start your Creamy Tuna Noodle Casserole by dicing your onion, slicing your mushrooms, and cooking your pasta according to the package’s instructions.
Then, heat some butter or olive oil in a pan and add the diced onion.
Sauté the onion until they start to brown, then add the mushrooms and some salt and pepper.
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.
Add the cooked, drained pasta to the bowl and stir.
Then you’ll add the canned chunk tuna to the bowl.
Next you’ll add the plain yogurt, garlic, and soy sauce.
Follow with the milk, and stir until everything is evenly coated.
Finish with freshly grated parmesan cheese, and season with additional salt and pepper.
Pour the tuna mixture into a casserole dish and spread evenly.
Top the casserole with bread crumbs and additional grated parmesan cheese.
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.
Serve and enjoy your Creamy Tuna Noodle Casserole.
- 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.
