Creamy Tomato Mushroom Pasta
When life gives you tomatoes, you make homemade mushroom tomato sauce! This meatless Creamy Tomato Mushroom Pasta with spinach is a filling vegetarian weeknight dinner for two you can make without needing to buy a jar of sauce.
Last month I talked about how I barely made it to any farmer’s markets this summer with my Tomato and Goat Cheese Pasta.
That post really got me thinking – why not? Why haven’t I taken the time to enjoy what makes me happy? Why was I not feeling motivated?
As I made more of an effort to go to the markets, I realized it was the timing.
There is supposedly a great farmer’s market in the city on Thursday afternoons, but the problem is it’s downtown during a weekday. Parking will either be nonexistent or cost me $10.
Then I have to time it just right so I don’t get caught in lunch or late afternoon rush hours. Not exactly motivating.
Saturdays are also popular for farmer’s markets, but Saturdays are also my busy days for errands usually not near these markets.
What about Sunday? Sundays are my slow days, days where I can take my time. My errands are done, so I can have more time to relax.
Turns out there is a Sunday farmer’s market about 15 minutes from me with free parking on the side streets.
This isn’t a tiny market either. When you first walk in, there’s a handful of tents. As you walk towards the end, you realize that isn’t the end and there are even more tents in the back. Tents full of produce fresh from farms!
Yes, there are a few people selling bread, jams, fresh coffee (cold brew!), and pizza for lunch, but the farmers outnumber the other tents.
There’s also a wide variety of produce available, more than just your zucchini and corn – tomatillos, heirloom tomatoes, bean sprouts, chard, a variety of peppers, fresh cut herbs, the list goes on.
I even went back the very next weekend with a friend because I wanted to share this market with someone.
Just walking around that market made me feel inspired again. I love cooking with fresh garden tomatoes.
When it’s summer, I try my best to buy tomatoes from farms and not the store because I can taste a difference.
Most of the time I end up making a quick pasta sauce with tomatoes, onion, garlic, and basil – very simple to highlight the freshness.
Even though my go-to recipe is similar to a marinara, I was in the mood for a creamier sauce; however, I didn’t want a super heavy sauce for summer.
That’s when I came up with this Creamy Tomato Mushroom Pasta with fresh spinach leaves.
It’s the tomato sauce you will want to make when you don’t have any jars in your pantry. It won’t take you hours to make either, making this dinner ideal for those busy weeknights.
What are shiitake mushrooms?
Lately I’ve been crushing on shiitake mushrooms, which have a meaty, earthy taste to them.
You often see them in Asian cuisine, but I bent the rules a little and went Italian because I love them so much.
I’ve seen them once at a farmer’s market because a mushroom farmer was there, but you can also find them in grocery stores.
Asian grocery stores sell them a bit cheaper than regular stores if you have any nearby.
If you don’t want to use shiitake, you can substitute any type of mushroom you want; most people love using white button or baby portobello mushrooms (aka cremini mushrooms) in pasta.
Be sure to use any extra mushrooms up in my Vegan Mushroom Gravy!
Which pasta should I use?
Speaking of pasta, there are certain shapes I like to eat over others, mainly because some shapes pair better than others with red sauce.
I knew I wanted to use a tube-like pasta to help hold the creamy tomato sauce with mushrooms, so I used penne.
Rigatoni is another great shape with ridges for the sauce to cling.
But really there’s no wrong answer. Although some shapes are better than others, use whatever you have in your pantry to make this pasta with mushrooms and tomatoes.
How To Make Tomato Mushroom Pasta
What I love about making homemade sauce is you can make it while the pasta is boiling. By the time the pasta is cooked, the sauce is ready to eat.
First, bring a large pot of unsalted water to a boil. I don’t salt it until I add the pasta because if you aren’t ready when your water boils, the water will reduce (which is a fancy way of saying the water boils off).
If you reduce salted water, the water gets saltier. And depending on the circumstances, it could become too salty to use.
By waiting to add the salt with the pasta, you’re less likely to have a disaster in the kitchen.
While the water is heating, start cooking your sauce in a large skillet.
Can you substitute canned tomatoes for fresh?
Although this recipe focuses on fresh tomatoes, you can use canned tomatoes when it’s not tomato season.
I prefer petite diced tomatoes because they’re smaller, but regular diced tomatoes work as well.
Because tomatoes vary in acidity, you may need to add 1 teaspoon sugar to balance the sauce.
Can you substitute frozen spinach for fresh?
I think using fresh spinach leaves are best, but in a pinch you can use frozen chopped spinach.
When the pasta is 1 minute from being done, add the frozen spinach to the boiling water and cook for 1-2 more minutes. That way you don’t need to dirty another pot.
My tomato sauce isn’t thickening. What should I do?
If your sauce is still a little thin, there are two ways you can thicken it:
- The best way to thicken a sauce is to cook it longer until it reduces. Reducing helps boil off some of the liquid, leaving you with a thicker sauce.
You do need to be careful with seasoning because the more it boils off, the saltier it’ll get. Let the sauce thicken to your liking before making final adjustments to taste.
- The tomato paste and cream cheese help thicken your creamy mushroom tomato sauce. If reducing doesn’t help, start by adding more tomato paste then adjust from there.
My tomato sauce is too thick. How do I fix this?
Fixing a thick sauce is much easier than fixing a thin sauce. Slowly stir in more broth until desired consistency is reached. Be careful you don’t overdo it, or you’ll have to cook it longer to re-thicken it.
Is this tomato mushroom pasta healthy for you?
Pasta sometimes gets a bad rap for being unhealthy, but it can be healthy when portioned correctly with a fresh sauce, like with my fresh tomato sauce, superfood spinach, and nutrient-filled mushrooms.
Pasta also supplies steady energy to get you through the rest of your day, especially if you have evening activities planned.

- 1/2 cup vegetable or chicken stock/broth
- 2 medium tomatoes, seeded and chopped or one (14.5 ounce) canned diced tomatoes, drained
- 1 teaspoon dried basil (or 1 tablespoon chopped fresh)
- 1 teaspoon dried oregano (or 1 tablespoon fresh)
- 1/4 teaspoon salt plus more to taste, preferably kosher
- Crushed red pepper flakes, to taste (optional)
- 2 ounces cream cheese, softened and cut into 8 pieces
- 1/4 cup grated Parmesan cheese
- 3 cups fresh spinach leaves
- 1 teaspoon granulated sugar (optional)
- Bring a large pot of water to a boil. Once boiling, add a big handful of salt then add penne. Cook as directed on the package until al dente, about 11-12 minutes. Drain into colander.
- Meanwhile, make the sauce: In a large skillet over medium heat, heat the olive oil until hot. Add the onion, mushrooms, and a big pinch of salt. Cook until softened, about 5 minutes. Add the garlic and cook 1 minute.

- Once boiling, turn the heat down to low then stir in the cream cheese and Parmesan cheese until melted.
- Add the spinach leaves and wait 30 seconds before stirring (as the spinach cooks, it'll shrink and be easier to stir). Cook for another 2-3 minutes or until wilted and bright green.
- Taste and adjust for seasoning. If the sauce is too acidic, add 1 teaspoon sugar. If it needs more salt, add more Parmesan cheese and/or salt.
- Add the cooked penne to the sauce and stir until coated.
