Instructions
Cook the pasta
Bring a large pot of salted water to a boil. Add penne pasta and cook until al dente, about 10 minutes. Drain and set aside.
Pro tip: Do not overcook the pasta as it will cook more in the oven.
Sauté the vegetables
In a large skillet, heat olive oil over medium heat. Add onions and cook until translucent, about 5 minutes. Add garlic and mushrooms, cooking until mushrooms are tender, about 7 minutes. Stir in dried thyme.
Pro tip: Ensure all water released from the mushrooms evaporates for best flavour.
Make the béchamel sauce
In a saucepan, melt butter over medium heat. Whisk in flour and cook for 1 minute. Gradually whisk in milk, continuing to whisk until the sauce thickens, about 5 minutes. Season with nutmeg, salt, and pepper.
Pro tip: Whisk continuously to avoid lumps in the sauce.
Combine ingredients
Preheat oven to 350°F (175°C). In a large bowl, combine cooked pasta, mushroom mixture, and béchamel sauce. Mix until well combined.
Assemble the casserole
Transfer the pasta mixture to a greased 9x13-inch baking dish. Sprinkle mozzarella and Parmesan cheese evenly over the top.
Pro tip: Spread cheese evenly for a uniform crust.
Bake the casserole
Bake in preheated oven for 25 minutes, or until the cheese is golden and bubbly. Let rest for 10 minutes before serving.
Pro tip: Resting helps the casserole set for easier slicing.
Tips & Tricks
- Use fresh portobello mushrooms for the best flavour.
- Pre-cook the pasta to al dente to avoid mushiness.
- Let the casserole rest before serving for easier slicing.
