Pumpkin Pizza with Caramelized Onions and Spinach

We'd love for you to share!

Pumpkin Pizza with Caramelized Onions and Spinach gives a delicious fall flare to pizza night. The pumpkin twist comes from creamy, cheesy Pumpkin Pasta Sauce that’s used instead of the red kind.

It’s the sauce I shared last week served over noodles…the same sauce I made batches and batches of so I could tell you with complete certainty that it was perfect. Luckily it freezes.

This combination is a bit adventurous for traditional pizza lovers. But, you’ll be glad you tried it. Next, you’ll be inspired to check out Butternut Squash Pizza too. It also uses caramelized onions and is equally delicious. 🙂

Tips to Make THE BEST Pumpkin Pizza

When you hear “Pumpkin Pizza” you might think of a crust infused with pumpkin or chunks of pumpkin as a pizza topping.

That’s not what’s happening here!

My youngest dd came up with the idea to use it on pizza and it was SUCH A GOOD ONE! We played with toppings until we came up with a delicious combination that perfectly complements the pumpkin sauce…caramelized onions and spinach.

Follow these tips for the best pumpkin pizza ever:

  • Use flat bread for the base to keep the calorie count down. Plus, it will cook very quickly.
  • Caramelize the onions. It’s totally worth it!
    • Plan ahead method – Make a big batch of Slow Cooker Caramelized Onions and defrost a portion for use in this recipe. It will become a 30 minute meal!
    • Just in time method – Use a mandolin (or knife) to thinly slice onions and cook them on the stove-top. This method will take about 30 minutes.
  • Julienne the spinach so it’s thin and pretty.

How to do it: Stack 5-6 spinach leaves on top of each other, roll them and then cut them into thin slivers with a knife or kitchen shears.

  • Use our secret sauce – Pumpkin Pizza Sauce! It will subtly add the flavor you are looking for.

Variations for Pumpkin Pizza

Other toppings or variations to try:

  • Flavor with sage instead of spinach – I so wanted to love crispy, fried sage on pumpkin pizza and I did give it a try. I wasn’t a big fan. But if you think you are and want to try this popular pairing, check out this video on how to fry sage leaves.
  • Apple slices or cubes
  • Mushrooms
  • Cheeses including Gruyere or Parmesan
  • Sausage, ham, prosciutto
  • Toasted pumpkin seeds
  • Toasted pine nuts

  • Return flat bread to the oven and cook for 4-5 minutes more or until cheese has melted.


Use one cup of Slow Cooker Caramelized Onion instead of making them scratch on serving day!

  1. Carmolized onions….. Pumpkin – Aw man, don’t even get me started… Oh wait, you did! lol!

  2. I want a fall party in my mouth! I love this idea…I was just tossing around something similar with pumpkin in a pasta sauce. And I would definitely have to throw on the fried sage leaves, as I look forward to them every fall.

  7. Love pumpkin! I imagine the sweetness of the pumpkin would go really well with all the other savoury ingredients. At first I thought your post title was pumpkin pizza, caramelized onions on cornbread… don’t know why I thought that, but if you ever need further inspiration, I think you should try this with cornbread!
