### **Instructions for Tuna and Mashed Potato Casserole**

#### 1. **Prepare the Mashed Potatoes**
Start by boiling the diced potatoes in a large pot of salted water. Bring the water to a boil, then reduce the heat and cook the potatoes for about 10-15 minutes, or until they are fork-tender. Drain the potatoes and return them to the pot.

#### 2. **Mash the Potatoes**
Add the butter, milk, sour cream, garlic powder, dried thyme, salt, and pepper to the potatoes. Mash everything together until smooth and creamy. Taste and adjust seasoning as needed. If you like extra creamy mashed potatoes, you can add more milk or sour cream.

#### 3. **Prepare the Tuna Mixture**
In a separate pan, sauté the chopped onion in a little bit of butter or oil over medium heat until it becomes soft and translucent, about 3-4 minutes. If you’re using frozen peas, add them in the last minute of cooking to heat through. Once the onion is cooked, add the drained tuna and stir until well combined.

#### 4. **Assemble the Casserole**
Preheat your oven to 375°F (190°C). In a greased baking dish (around 9×9 inches), spread the tuna mixture evenly on the bottom. Then, spread the mashed potatoes over the top, smoothing them out to cover the entire surface.

#### 5. **Top with Cheese and Breadcrumbs**
Sprinkle a generous amount of shredded cheddar cheese over the mashed potatoes. For extra crunch, you can sprinkle breadcrumbs on top as well. If you want a golden, crispy top, lightly spray the breadcrumbs with cooking oil or drizzle with a bit of melted butter.

#### 6. **Bake the Casserole**
Place the casserole in the oven and bake for 20-25 minutes, or until the cheese is melted and bubbly and the top is lightly golden. If you used breadcrumbs, they should be crispy and golden-brown.

#### 7. **Serve and Enjoy**
Once the casserole is done, remove it from the oven and let it cool for a few minutes before serving. This dish pairs perfectly with a simple salad or steamed vegetables for a complete meal.

### **Tips for the Perfect Tuna and Mashed Potato Casserole**

– **Customizable Veggies**: Add other vegetables such as corn, bell peppers, or carrots to the tuna mixture for extra flavor and nutrients. You can also use leftover vegetables from other meals.
