Ingredients

  • 12 oz elbow macaroni (consider gluten-free)

  • 2 tablespoons olive oil

  • 1 small yellow onion, finely chopped

  • 2 tablespoons all-purpose flour (or gluten-free flour blend)

  • 2 cups unsweetened almond milk (or oat milk for a creamier texture)

  • 2 tablespoons nutritional yeast

  • 1/2 teaspoon garlic powder

  • 1/2 teaspoon onion powder

  • 1/2 teaspoon salt

  • 1/4 teaspoon black pepper

  • 2 cans (5 oz each) tuna, drained and flaked

  • 1 cup frozen peas (optional)

  • 1/2 cup dairy-free shredded cheese (optional topping)

Directions

  • Cook the elbow macaroni according to package directions. Drain and set aside.
  • Heat olive oil in a saucepan over medium heat. Add the chopped onion and cook until soft, about 4 minutes.
  • Stir in flour and cook for 1 minute, then slowly whisk in almond milk.
  • Add nutritional yeast, garlic powder, onion powder, salt, and pepper. Cook, whisking, until the sauce thickens slightly, about 3–5 minutes.
  • Remove from heat and stir in tuna and peas (if using).
  • Mix the sauce with cooked noodles and transfer to a greased 9×13-inch baking dish.
  • (Optional) Sprinkle dairy-free shredded cheese on top.
  • Bake at 375°F for 20–25 minutes, or until hot and bubbly.

Notes

  • Nutritional yeast adds a cheesy flavor without dairy — don’t skip it if you can help it!
