Spinach Mushroom French Bread Pizzas

The other day I needed something really fast and easy for lunch and I was craving Swiss cheese (weird, right?). Well, my solution to that problem was this: sauté up some mushrooms and garlic, add some frozen spinach, pile it onto bread, cover it with Swiss, and broil until melted. Super fast, easy, and delicious. I got my pizza fix and vegetable quota all in one swoop. Spinach Mushroom French Bread Pizzas for the win!

Balancing the Cost

Mushrooms and Swiss cheese tend to be more on the expensive side of the ingredient price spectrum, so I balanced out the cost of this recipe by pairing them with two inexpensive ingredients: frozen spinach and French bread (the soft fluffy kind that you find in most grocery store bakeries). With a final price of $1.44 per pizza, I could definitely afford to eat two if I was super hungry. I’ve been reheating the leftovers in the microwave and although they’re not crispy that way, they’re still quite delicious. A toaster oven would be ideal for reheating.

What About Pizza Sauce?

I didn’t use pizza sauce on these “pizzas” because I didn’t have any on hand, so they’re kind of like an open faced grilled cheese. But if you happen to have leftover pizza sauce (because sometimes that happens) you can spread a layer onto the bread before the spinach and mushrooms, or just dunk your French bread pizza into a small dish of sauce.

Can I Substitute the Swiss?

Sure, if you’re not into Swiss cheese you can swap it out for a more classic mozzarella cheese. Either shredded or sliced will work fine. If you’re using shredded, you can experiment with mixing it right into the spinach and mushroom mixture before piling it onto the bread, then it will create a nice melty mixture.

Prep Time: 10 mins

Total Time: 30 mins
Servings: 4

Ingredients

  • 3 Tbsp olive oil, divided ($0.48)
  • 2 cloves garlic, minced ($0.16)
  • 8 oz. button mushrooms ($1.99)
  • 8 oz. frozen spinach ($1.17)
  • salt & pepper to taste ($0.05)
  • 1 16-inch loaf French bread ($0.90)
  • 4 slices Swiss cheese ($1.01)

Instructions

  • Wipe the mushrooms clean, then slice thinly. Add 1 tablespoon of olive oil to a large skillet along with the minced garlic. Sauté the garlic over medium heat for one minute or just until fragrant. Add the sliced mushrooms and sauté for 3-5 minutes more, or until they are limp and dark brown (add a pinch of salt to help them release their moisture if needed).
  • Add the frozen spinach to the skillet and continue to sauté until it is heated through. Season the mushrooms and spinach with salt and freshly cracked pepper to taste (I used about 1/4 tsp salt and 10 cranks of a pepper mill.
  • Adjust your oven rack so that the top of the French bread will be 5-6 inches from the broiler unit. Preheat the broiler on high for a few minutes. While it's heating, cut the loaf of French bread into two 8 inch sections, then slice each piece in half lengthwise to open like a sandwich.
  • Line a baking sheet with foil. Place the pieces of French bread on the baking sheet open side up. Brush the remaining 2 tablespoons of olive oil over the open surface of the bread. Place the bread under the broiler for about 3 minutes, or just until it is golden brown.
  • Top each piece of bread with 1/4 of the spinach and mushroom mixture, and one piece of swiss. Return the topped bread to the oven and broil for 1-2 minutes, or just until the cheese is hot and bubbly. Watch them closely to prevent burning. Serve hot.

How to Make Spinach Mushroom French Bread Pizza – Step by Step Photos

Frozen Spinach Package and a pint of Mushrooms

For this recipe I used one 8oz. container of button mushrooms and about 8oz. (1/2 lb.) of frozen spinach. The bag of frozen spinach is 12oz., so I just estimated 2/3 of the bag. You can add a little more or less without it hurting the recipe. Wipe the mushrooms clean, then slice them into thin pieces.

Sautéed Mushrooms in a skillet with a wooden spoon

Add 1 Tbsp of olive oil to a large skillet, along with 2 cloves of minced garlic. Sauté the garlic for about a minute over medium heat, or just until it becomes a little soft and fragrant. Add the sliced mushrooms and continue to sauté until the mushrooms become limp and dark brown. The mushrooms will initially soak up all the oil and the skillet will appear dry, but once they begin to heat they will let off liquid. You can add a pinch of salt to help the mushrooms expel their moisture.

Sautéed Spinach with mushrooms in the skillet

Add the 8oz. of frozen spinach and continue to sauté until the spinach is thawed and heated through. Season the skillet with salt and pepper to taste. I added about 1/4 tsp salt and a healthy dose of freshly cracked pepper.

Two loaves of French Bread

I got this twin pack of French bread for $1.79 and each piece was about 16-17 inches long. I ended up only using one. Cut the French bread in half to make two 8-inch sections. Then cut the sections open as if you were going to make a sandwich. You should now have four pieces.

Oil spread on cut Bread

Adjust your oven rack so that the top of the French bread will be 5-6 inches away from the broiler unit. Preheat the broiler for a few minutes. Meanwhile, cover a baking sheet with foil, then place the French bread pieces on the baking sheet with cut sides up. Brush the remaining 2 Tbsp of olive oil over the open surface of the bread. Broil the bread for about 3 minutes, or just until it becomes light golden brown.

Slices of Swiss cheese added on top of spinach and mushroom bread

Once the bread is golden brown and a little crispy, take it out of the oven and top each piece with 1/4 of the spinach mushroom mixture. Top each bread with one slice of Swiss Cheese. I tore my slices in half to better cover the long bread.

Pop the bread back under the broiler for just a couple minutes or until the cheese is hot and bubbly. This will happen quickly, so keep a close eye. The pizza is ready to eat!
