Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish with olive oil or another oil of your choice.
Cook the pasta according to the package instructions until just al dente. Drain and set aside.
In a large skillet or saucepan, heat the olive oil over medium heat. Add the diced onion and carrots, cooking for 4-5 minutes until they begin to soften. Add the minced garlic and cook for 1 more minute until fragrant.
In a bowl or measuring cup, whisk together the coconut milk, chicken or vegetable broth, and arrowroot flour. Pour this mixture into the skillet with the vegetables, stirring constantly. Cook until the mixture thickens, about 4-5 minutes.
Stir in the nutritional yeast, lemon juice, salt, and black pepper. Adjust seasoning to taste.
Add the drained tuna, peas, and cooked pasta to the skillet, gently stirring to coat everything evenly with the sauce.
Transfer the mixture to the prepared casserole dish, spreading it out evenly. If desired, sprinkle the gluten-free breadcrumbs over the top for a crunchy finish.
Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbling and the breadcrumbs (if used) are golden brown.
Remove from the oven, let cool for 5 minutes, and serve warm.
