Baked Cheesy Chicken Penne
slightly adapted from this recipe by Martha Stewart

• 6 tablespoons butter, plus more for baking dishes
• kosher salt and black pepper
• 1 pound penne rigate
• 1 teaspoon olive oil
• 2 boneless, skinless chicken breast halves (about 8 ounces each), halved horizontally
• 1/2 cup plus 2 tablespoons flour
• 6 garlic cloves, finely minced
• 6 cups whole milk
• 10 ounces white or cremini mushrooms, trimmed and thinly sliced
• 1 cup sliced oil-packed sun-dried tomatoes, drained
• 1 1/2 cups shredded provolone* (6 ounces) you could also make that 1/2 mozzarella
• 1 1/2 cup freshly grated Parmesan (about 6 ounces)

*Note on Cheese: 
Sometimes provolone cheese can be hard to find.  I don’t always encourage the use of pre-shredded bagged cheeses (because ‘ve found they usually contain additives and therefore don’t melt or taste as good), but in this recipe I’ve used a *good* quality one, like Sargento, and it’s turned out great.  Actually in this batch I used Sargento’s Provolone/Mozzarella mix.  You’ll find that with packaged cheese mixes, provolone is often mixed with other white cheeses and that’s totally fine.  Just try to find one that is mostly provolone, like a 50/50 mix.  The other easy option is to go to the deli department where you can buy sliced cheese.  Just ask for a 6 oz chunk and you can grate it yourself.

Directions

1. Preheat oven to 400. Butter two shallow 2-quart baking dishes. If you’re going to freeze one, use a disposable foil pan.  In a large pot of boiling salted water, cook pasta 3 minutes short of al dente; drain pasta and set aside.
2. While pasta is boiling, heat oil over medium-high heat in a large skillet. Season chicken with salt and pepper; cook until opaque throughout, 3 to 5 minutes per side. Halve each piece lengthwise, then thinly slice crosswise.  While chicken pan is still hot, toss the mushrooms in and saute until golden brown (3-4 minutes).  Use a little extra olive oil if needed.
3. In a 5-quart Dutch oven or heavy pot (I just use the pot I cooked my pasta in), melt butter over medium. Add flour and garlic; cook, whisking, 1 minute. While whisking constantly, gradually add milk; bring to a simmer.  Keep whisking frequently as sauce thickens, about 1 minute more. Add mushrooms and tomatoes; cook 1 minute. take the pan off the heat and and gradually stir in provolone and 1/2 cup Parmesan.
4. Add chicken and pasta to pot; season with salt and pepper to taste. Divide pasta mixture between baking dishes.  If freezing, place remaining parmesan cheese in a zip-top baggie.  If cooking, sprinkle on top.
5. Bake, uncovered, until top is golden and bubbling, about 25 minutes. Let stand 5 minutes before serving.

Freezer instructions:
To freeze, prepare through step 4 and then let pasta cool.  Cover pan well with plastic wrap.  Place extra cheese in baggie (for topping) on top and then cover entire pan well with foil.  Freeze for up to 3 months.  To bake, preheat oven to 400.  Remove foil and plastic from pan and set cheese baggie aside.  Place foil back on pan and bake for about 1 1/2 hours.  Remove foil, stir pasta, and top with cheese.  Return pan to oven and bake for an additional 15 minutes or until mixture is hot and bubbly throughout.
