Ingredients

  • 2 tablespoons olive oil
  • 170 grams chopped mushrooms
  • 1 chopped white onion
  • 1 chopped green bell pepper
  • 10 grams minced garlic
  • 1.5 grams salt
  • 2 grams black pepper
  • 1 gram thyme
  • 267 grams peas
  • 280 grams dry pasta
  • 226 grams plain greek yogurt
  • 3 cans drained tuna
  • 30 grams grated parmesan cheese
  • 112 grams cheddar cheese
  • 1 cup bone broth
  • 1/2 cup unflavored milk or milk substitute (like almond milk)
  • 10 grams grated parmesan cheese (for topping)
  • 30 grams bread crumbs (for topping)
 

Step 1: Sauté the Vegetables

Heat a stovetop pan over medium-high heat and add 2 tablespoons of olive oil.

Once the oil is heated, add 170 grams of chopped mushrooms, 1 chopped white onion, 1 chopped green bell pepper, 10 grams of minced garlic, 1.5 grams of salt, 2 grams of black pepper, and 1 gram of thyme.

Stir and cook for a few minutes until the vegetables are tender.

Add 267 grams of peas to the pan and cook for another couple of minutes, allowing more time if using frozen peas.

 

Step 2: Cook the Pasta

While the vegetables are cooking, prepare 280 grams of dry pasta according to the package instructions, but cook it for 1 to 2 minutes less than the recommended time to ensure it remains al dente.

Drain the pasta and set it aside.

 

Step 3: Combine Ingredients in Mixing Bowl

In a large mixing bowl, combine the cooked pasta with the sautéed vegetable mix.

Add 226 grams of plain Greek yogurt, 3 cans of drained tuna, 30 grams of grated Parmesan cheese, 112 grams of cheddar cheese, 1 cup of bone broth, and 0.5 cup of unflavored milk or milk substitute.

Mix until all the ingredients are well incorporated.

 

Step 4: Assemble the Casserole

Pour the mixture into a 2-quart casserole dish and spread it out evenly.

Top with an additional 10 grams of grated Parmesan cheese and 30 grams of breadcrumbs for a delicious, crunchy topping.

 

Step 5: Bake and Broil

Cover the casserole dish with foil and bake in the oven at 375°F (190°C) for 35 to 40 minutes.

After baking, remove the foil and switch the oven to broil for a few minutes until the top is golden brown.

Watch closely to prevent burning.

 

Step 6: Serve or Store

Allow the casserole to cool slightly before serving.

This dish can also be portioned into meal prep containers if you’re planning to store it for later consumption.

Enjoy your hearty and nutritious tuna noodle casserole!
