My 1968 Better Homes & Gardens cookbook has a classic tuna casserole recipe that calls for mayonnaise, milk, and cream of celery soup. Now, I love a good old-fashioned casserole, but I couldn’t help thinking there had to be a way to make it a little lighter without losing everything that makes it so comforting.
That’s how this gluten-free tuna pasta bake came about! I traded the traditional creamy soup base for a lighter Parmesan and garlic sauce, added fresh spinach and red bell peppers, and finished everything with a golden, crispy topping.
And you know what? It’s still delicious! It’s creamy, comforting, full of flavor, and made right in one skillet. Sometimes the classics just need a little updating.
Why You’ll Love This Gluten-Free Tuna Pasta Bake
- One skillet, less cleanup. The gluten-free pasta cooks right in the seasoned broth, so there’s no separate pot of boiling water or pasta to drain.
- Comfort food with a lighter touch. Milk, chicken broth, and Parmesan create a creamy sauce without mayonnaise or condensed soup.
- More vegetables, more color. Sweet red bell peppers and fresh spinach bring flavor, texture, and a little extra goodness to every bite.
- Pantry-friendly protein. Canned tuna makes this an easy dinner when you haven’t planned ahead.
- That golden topping! A little gluten-free panko and Parmesan give the casserole the crispy finish that makes it feel like the classic.
A Comfort Food Classic, Made a Little Lighter
One of the things I love about revisiting older recipes is seeing how much our cooking has changed. That 1968 cookbook is full of recipes built around convenience ingredients, and there’s certainly something to be said for getting dinner on the table without a lot of fuss.
But convenience doesn’t have to mean opening a can of condensed soup.
In this version, the pasta cooks directly in the broth, soaking up all that garlic and basil flavor. A little milk and Parmesan bring everything together, and the spinach wilts right into the sauce.
The tuna goes in toward the end so it stays in nice chunks instead of disappearing into the pasta.
And because I couldn’t leave well enough alone, there’s a crispy Parmesan-panko topping. Some things are simply too good to give up!
Golden Skillet Tuna Pasta Bake with Spinach & Red Peppers
Golden Skillet Tuna Pasta Bake with Spinach & Red Peppers
Ingredients
- 8 ounces dry gluten-free fettuccine or fettuccine
- 1 tablespoon olive oil
- 1 medium red bell pepper diced
- 3 garlic cloves minced
- 3 cups fresh baby spinach roughly chopped
- 2 5-ounce cans tuna packed in water, drained
- 1 cup 2% milk
- 3 cups low-sodium chicken broth
- 2 tablespoons cornstarch
- ÂĽ cup freshly grated Parmesan cheese
- 1½ teaspoons dried basil
- ½ teaspoon kosher salt
- ÂĽ teaspoon freshly ground black pepper
- 1 teaspoon fresh lemon juice
- 2 tablespoons gluten-free panko breadcrumbs
- 2 tablespoons freshly grated Parmesan cheese
- 1 teaspoon olive oil
- 1 tablespoon chopped fresh parsley
Instructions
- Heat 1 tablespoon olive oil in a 12-inch oven-safe skillet over medium heat. Add the diced red bell pepper and cook for 4–5 minutes, stirring occasionally, until softened. Add the garlic and cook for 30 seconds.
- Pour 3 cups chicken broth into the skillet. Stir in the dried basil, salt, and pepper. Bring to a gentle boil, then add the uncooked gluten-free fettuccine. Stir well to distribute the pasta evenly.
- Reduce the heat to medium-low, cover, and simmer gently for approximately 9–13 minutes, depending on the pasta brand. Stir every 2–3 minutes to prevent sticking. Add additional broth, ¼ cup at a time, if the skillet becomes dry before the pasta is tender. The pasta should be just shy of al dente.
- Reduce the heat to low. Stir in the milk and chopped spinach. Cook uncovered for 2–3 minutes, stirring gently, until the spinach wilts and the pasta is tender. If the sauce seems too thin, whisk 1 tablespoon cornstarch with 2 tablespoons cold water and stir it into the simmering sauce. Cook for 1 minute until thickened.
- Remove the skillet from the heat. Stir in ÂĽ cup Parmesan cheese and the lemon juice. Gently fold in the drained tuna, keeping it in large chunks. The sauce should be creamy and slightly loose because it will continue thickening as it rests.
- In a small bowl, combine the gluten-free panko, remaining 2 tablespoons Parmesan, and 1 teaspoon olive oil. Sprinkle evenly over the pasta.
- Place the skillet 4–6 inches from the preheated broiler and broil for 1–2 minutes, watching carefully, until the topping is lightly browned and crisp.
- Remove the skillet from the oven, sprinkle with fresh parsley, and serve immediately.
Notes
Can You Make This Tuna Pasta Bake Dairy-Free?
Absolutely! The recipe is already gluten-free when you use gluten-free pasta, certified gluten-free panko, and gluten-free broth.
For a dairy-free version, substitute plain, unsweetened dairy-free milk for the regular milk and use a dairy-free Parmesan alternative in the sauce and topping. Choose an unflavored milk that works well in savory dishes, and check your Parmesan substitute for gluten-containing ingredients.
The finished sauce may have a slightly different flavor and consistency, but you’ll still have a comforting skillet dinner.
A Little Nostalgia, A Little Less Work
There’s something special about the recipes we grew up with. They remind us of family dinners, familiar flavors, and a time when casseroles were practically their own food group.
I don’t think we need to give those recipes up. Sometimes we just need to find a way to make them work for how we cook and eat today.
This gluten-free tuna pasta bake keeps the creamy comfort and golden topping I remember, adds a few colorful vegetables, and makes cleanup easier along the way.
And if you’ve got an old family cookbook tucked away somewhere, maybe it’s time to pull it out. You never know which recipe might deserve a second life.
Because great food brings people to the table. Meaningful moments keep them there.
Save me a bite!
