2. **Prepare Baking Dish:**

- Preheat oven to 350°F (175°C).

- Grease a 9 x 12-inch baking dish with 2 tablespoons of butter.

3. **Cook Vegetables:**

- Heat olive oil in a large skillet over medium heat.

- Sauté the diced green pepper, diced onion, and sliced mushrooms for 3-4 minutes until softened.

4. **Cook Beef:**

- Add the ground beef to the skillet with the vegetables. Season with kosher salt and black pepper.

- Cook until the beef is no longer pink, breaking it into small pieces as it cooks. Drain any excess fat.

5. **Add Sauce:**

- Pour the pasta sauce into the skillet with the beef and vegetable mixture. Stir to combine and heat through.

6. **Prepare Cheese Mixture:**

- In a medium mixing bowl, combine the softened cream cheese, sour cream, and cottage cheese.

- Use a hand mixer or immersion blender to blend until smooth.

7. **Assemble:**

- Spread half of the cooked pasta in the bottom of the greased baking dish.

- Evenly spread the cheese mixture over the pasta.

- Add the remaining pasta on top, followed by the beef and sauce mixture.

8. **Bake:**

- Cover the dish with foil (spray foil with oil to prevent sticking).

- Bake for 20 minutes.

- Remove foil, sprinkle grated cheese on top, and return to the oven for another 10-15 minutes until the cheese is melted and bubbly.

9. **Serve:**

- Let the dish rest for 5 minutes before serving.
