Cheesy Baked Mushroom Penne Florentine

If you are a mushroom lover, you will love this baked pasta dish!  It’s a great combination of both fresh and dried mushrooms, that are nestled in a creamy, cheesy sauce, then topped off with more cheese, because why not?  To make it fun and “fancy”, I baked the pasta in individual ramekins so everyone gets their own.

Let’s talk about the dried mushrooms for a minute.  I used a mixture of shiitake, oyster and porcini mushrooms that I got at Trader Joe’s.  Before these are added to the dish, they take a nice long soak in hot water to re-hydrate them.  The wonderful thing about this is that the water then turns into a deeply flavored mushroom broth…do.not.throw.this.away!  This flavorful broth goes right into the creamy, cheesy sauce.  The broth gives the sauce a deep, almost smoky flavor, trust me, it’s really incredible.  You may even think there’s bacon in the dish, in fact, both Kelly and Steve asked if there was.  It’s sure to please vegetarians and meat eaters alike!

I baked this in individual ramekins, because I thought that would be fun, but if you prefer, you can totally bake this in a 9×13 pan.  It can also be made ahead, refrigerated and baked when you’re ready.  You’ll just need to add another 5-10 minutes of baking time.
