🤔 FAQs

These are the questions we are most frequently asked about making the rigatoni casserole with gremolata topping.

Do you have to boil pasta before baking?

Yes. If you add uncooked pasta to the baking dish, it won’t cook all through by the end of the cooking time.

Can you bake raw pasta?

It’s possible to bake raw pasta, but then you must increase the baking time so the pasta is cooked all through. You may also need to cover the baking dish with foil for part of the baking so that the topping doesn’t burn.

What is it called when you bake pasta?

Baking pasta in a casserole dish is often called ‘pasta bake’!

Why is my baked pasta dry?

The pasta absorbs liquid from the sauce and other moist ingredients in a dish while it bakes. If your pasta bake is dry, then it’s an indication that there was too much pasta and not enough liquid.

👩🏻‍🍳 Tips

  • When using a blender to puree the mushrooms and creamy sauce, allow the mixture to cool slightly first (about 5 minutes) and fill the blender only halfway. Leave one corner open when placing the lid on. You can catch any splatters by covering the lid with a kitchen towel. Pulse until smooth. 
  • The reserved pasta water can be added to the bowl of pasta and sauce just before transferring it to the prepared baking dish to achieve the desired consistency, adding extra liquid to the dish without diluting any flavor. 
  • Pasta usually takes around 8 minutes to cook through, but I usually shave off a minute or 2 to achieve al dente pasta so that by the time the semi-cooked pasta has cooked further in the heated sauce mixture and baked, it’s not overcooked.

📚 Variations

  • Any other pasta can be used for this dish. I prefer short and tubular pasta variations since they are great for “catching” the sauce. 
  • Heavy cream can be used in place of the milk when making the sauce which will certainly add to the flavor, but you may need to thin it with reserved pasta water.
  • If you crave a meaty pasta bake, incorporate some ground beef or chunks of sausage into the casserole.
  • While this is a 2-cheese pasta bake recipe, you can make a 3-cheese version by adding another cheese favorite like grated Mozzarella cheese.
  • You can use store-bought mushroom pasta sauce instead of making the sauce from scratch.

🥫 Storage

Store leftover baked mushroom rigatoni with kale gremolata in the refrigerator for 3-4 days in an airtight container or the casserole dish, covered tightly in plastic wrap. 

This pasta bake can also be stored in the freezer for up to 3 months. Thaw overnight in the refrigerator and reheat in the oven, covered with aluminum foil, so the topping doesn’t burn.

Do you ever find yourself craving a comforting meatless casserole? I know I do from time to time, although I still love the rich flavor of meat which is why this baked mushroom rigatoni with kale gremolata is such a great choice!

The seared mushrooms provide a rich meaty flavor and texture among the creamy sauce and tender pasta. 

The gremolata topping adds an irresistible crunch to this soft pasta bake. It’s the kind of pasta bake I’m incredibly proud to present to family and guests for special occasions, as well as whipping it up for a midweek family dinner!

Get Recipe Ingredients

Instructions

Pasta:

  • Cook the rigatoni in a large pot of generously salted boiling water until al dente, about 3 minutes less than the package directions. Drain, reserving ½ cup of the cooking water.

Rigatoni bake:

  • Preheat the oven to 375 degrees℉.
  • Heat the olive oil over medium-high heat in a large Dutch oven. Sear the mushrooms, undisturbed, for 3 minutes; stir, and season with 1 teaspoon salt. Sear on the reverse side an additional 2 minutes. Remove the mushrooms from the pan and set aside.
  • Lower the heat to medium and melt the butter in the Dutch oven. Add the garlic and flour, and cook, stirring, for 1 minute. Whisk in the milk and simmer gently until the sauce just thickens, 5 minutes.
  • Remove from the heat and add the parmesan, Gruyere and ½ teaspoon salt. Let cool slightly, then add ½ of the seared mushrooms, and puree with an immersion blender. (See notes if using blender)
  • In a large bowl, toss the pasta with the sauce and the remaining half of the mushrooms, adding about ¼ cup of the reserved pasta water or more if desired.
    Transfer to a buttered baking dish.

For the gremolata:

  • In a medium bowl, combine the kale, Gruyere, panko, smoked almonds, olive oil and lemon zest.
  • Scatter the gremolata over the pasta and bake until golden on top and bubbling, about 40 minutes.

Notes

If using a blender to puree:  first let the hot liquid cool for five minutes or so, then transfer it to a blender, filling only halfway. Put the lid on, leaving one corner open. Cover the lid with a kitchen towel to catch splatters, and pulse until smooth.
