Spinach Pasta Bake Variations and Substitutions

• Feel free to use a homemade pasta sauce instead. I always love using homemade sauces, but since this recipe is focused on busy weeknights, I decided to go with a jar of marinara sauce (opens in a new tab) instead. This one is so good!
• Add a little bit of parmesan cheese over the top to really take the cheesy goodness up a notch!
• This recipe is vegetarian, but you can also add any type of protein of choice (chicken, ground beef, sausage).
• Top with fresh oregano and red pepper flakes for an extra delicious meal!

Serving Suggestions for Spinach Pasta Bake

This easy pasta bake is a complete meal on its own, but it’s also easy to pair with other dishes if you want to round things out. Here are some of my favorite ways to serve it:

• With a fresh side salad – Something crisp and tangy like my Shaved Fennel Salad, which balances the richness of the pasta.
• Garlic bread or crusty baguette – Because extra carbs are always a good idea when there’s cheesy sauce involved!
• Roasted vegetables – Try garlic roasted broccoli or these Easy Roasted Carrots for a side.
• Soup and pasta night – Pair it with a lighter soup like Homemade Tomato Soup for the ultimate cozy dinner.
• Topped with fresh herbs and red pepper flakes – Adds a pop of color and just a little heat.

How to Store Mushroom and Spinach Pasta Bake

Store leftovers in an airtight glass container (since the pasta sauce can stain plastic)! This recipe can last in the refrigerator for 3-5 days or the freezer for up to 3 months.

To freeze, let cool in the fridge for 1 hour before moving to the freezer. When ready to enjoy, reheat from frozen in the microwave or put it back in the oven until everything is warm!
