Make Pumpkin Pizza with easy pumpkin pizza sauce, caramelized onions, and spinach. Or, use our ultimate toppings list to create your own masterpiece. It's an easy way to give a seasonal twist to pizza night.
Creamy pumpkin pasta sauce stands in for marinara to give this pizza a subtle fall flair. By the way, the same sauce can be used for your favorite pasta dishes too!
When you hear "Pumpkin Pizza," you might think of roasted squash cubes like our Butternut Squash Pizza. Or, you might imagine a crust infused with pumpkin.
That's not what's happening here.
The pizza sauce and the caramelized onions can both be made in advance. If they are, and you use flatbread as the base, then this dinner is ready in about 10 minutes!

Ingredients and Substitutions
Here's what you need to make pumpkin pizza:
- Flatbread or Pizza Dough - We used flatbread because it bakes quickly and reduces the calorie count too. Most any base will work, including spaghetti squash pizza crust.
- Caramelized Onions - The process to make these is discussed below.
- Spinach - Chopped kale and arugula are alternatives.
- Mozzarella Cheese - Havarti, fontina, and Gruyère would be nice too.
- Pumpkin Pizza Sauce - The ingredients to make it are shown below. You can often find this type of sauce in the grocery store in the cooler months.
For the pumpkin sauce, you will need the items pictured. Half and half or whole milk may be used instead of heavy cream if desired.
Pumpkin Pizza Sauce Directions
This versatile pumpkin sauce works well in this recipe because it's smooth, just like traditional sauce. However, the consistency is a little thicker than a red sauce. If you want to thin it out, simply add a teaspoon of water. Taste test before adding more.
Here are the steps to make it:
- Heat olive oil over medium heat in a medium-sized saucepan. Add garlic and sauté for about 1 minute to soften.
- Add pumpkin puree, heavy cream, nutmeg, salt, and pepper to the pan.
- Whisk until smooth. Bring sauce to the point where it's just about to boil and then reduce heat to simmer and cook for about 4-5 minutes.
- Stir in Parmesan cheese.
Yield: 2 cups of sauce. Each serving is ⅓ of a cup.
Note: This recipe makes more sauce than you will need to make 4 servings.
Storage: Store pumpkin pizza sauce in a covered container in the refrigerator for 3-4 days or in the freezer for up to 3 months. Defrost overnight in the refrigerator.
Reheat: Sauce may be used hot or cold. Warm over medium-low heat on the stovetop, stirring to recombine ingredients.
How to Caramelize Onions
Caramelized onions pair perfectly with pumpkin in this recipe. The extra effort is totally worth it too!
If you made a big batch of Slow Cooker Caramelized Onions, just defrost a portion for use in this recipe!
Otherwise, follow these steps to make them on the stovetop.
- Melt butter and olive oil in a large skillet.
- Add thinly sliced onions (about ⅛ inch in thickness) to the pan and coat with butter/oil mixture.
- Cook onions for 20-30 minutes over medium heat, stirring and scraping up brown bits every 3-5 minutes. The onions need undisturbed time so they can brown. But, they can't sit for too long because they will burn. If the pan becomes too dry, then add a teaspoon of water. Picture #3 is at 5 minutes.
- When the onions are browned to your liking, remove them from the pan. You can also deglaze the pan with a little balsamic vinegar or wine to add even more flavor.
Note: The best pan for this process is a cast iron skillet. But, onions can be caramelized in a non-stick skillet, which I used in the pictures.
Pumpkin Flatbread Pizza Assembly
Here's how to put it together.
But first, pre-cook the flatbread (or pizza dough.) We use Flatout Thin Pizza Crusts. The directions all for the crusts to bake at 375 °F for about 2 minutes!
- Spread pumpkin pizza sauce over the flatbread.
- Top with caramelized onions.
- Chop spinach into thin slices and sprinkle over the top.
- Easy way to julienne spinach: Stack 5-6 spinach leaves on top of each other, roll them long ways, and then cut them into thin slivers with a knife or kitchen shears.
- Sprinkle mozzarella cheese over the top and bake for about 5 minutes or until the cheese is melted.
Suggested quantities are listed in the recipe card. Of course, adjust everything according to your preferences!
Toppings for Pumpkin Pizza
Other toppings or variations to try:
- Flavor with sage instead of spinach - I so wanted to love crispy, fried sage and I did give it a try. I wasn't a big fan.
- Apple slices or cubes
- Crumbled Bacon
- Mushrooms (you can cook these along with the onions!)
- Sausage, ham, prosciutto
- Toasted pumpkin seeds
- Toasted pine nuts

This is such an amazing idea. I made a different pumpkin yogurt sauce last week and I think I could use up my saved sauce on a pizza like this. Awesome, thanks!

I have made this flatbread twice. I added more nutmeg to the pumpkin sauce and used goat cheese in the second round. Awesome changes! Definitely would recommend making this.
