Ingredients for 21 day fix pizza
Crispy crust, protein-packed toppings—all the pizza flavor, none of the guilt. Here’s what you’ll need for a 21 Day Fix-friendly slice.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Cauliflower 🥬 | 12 oz | Riced with food processor |
| Large Egg Whites 🥚 | 4 whole | Room temperature preferred |
| Almond Flour 🌰 | 1 ½ cups | Blanched preferred |
| Low-Fat Mozzarella Cheese 🧀 | 1 cup | Part-skim, shredded |
| Light Tomato Sauce 🍅 | ½ cup | No sugar added |
| Red Bell Pepper 🌶️ | ½ cup | Diced, fresh |
| Fresh Spinach 🍃 | 1 cup | Chopped, loosely packed |
| Garlic Cloves 🧄 | 2 cloves | Minced for sauce |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for crust |
| Baking Powder 🧂 | ½ tsp | For crust lift |
| Salt 🧂 | ½ tsp | Kosher preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Italian Seasoning 🍃 | ½ tsp | Dried blend |
The cauliflower is the star here, and freshness matters. Grab a head from the produce section—look for bright white florets with no yellowing. Trader Joe’s and Whole Foods usually have the best quality. Ricing it yourself (no pre-riced cauliflower here!) gives you that perfect texture. If you’re short on time, Costco’s frozen riced cauliflower works in a pinch, but drain it well. The egg whites need to be room temp—just take them out of the fridge 10 minutes before using for best results. Almond flour? Bob’s Red Mill is my go-to brand—it’s finely ground and blends perfectly with the cauliflower.
No fresh spinach? Baby spinach works too, but chop it finely since it wilts fast. Short on bell pepper? Mushrooms or zucchini add great texture. The tomato sauce is where flavor happens—Rao’s no-sugar-added is my secret, but any low-sugar marinara works. Want extra protein? Add a sprinkle of low-fat cottage cheese before baking. The Italian seasoning blend is key—if you don’t have it, dried oregano plus basil works in a pinch. And yes, you can use regular mozzarella if that’s what you’ve got, but part-skim keeps it 21 Day Fix approved.
Prep the crust ahead and store it in the fridge for up to 24 hours—just bake straight from cold. The toppings can be prepped separately and kept in the fridge for 1 day. Baked pizza reheats beautifully—30 seconds in the microwave or 5 minutes at 350°F to crisp it up again. Portion control tip: one 10-inch pizza = one container. Freeze crusts without toppings for up to 2 months—just add toppings and bake straight from frozen (add 5 minutes).

Step-by-step instructions for crispy cauliflower crust pizza
Here’s how to make a crispy, protein-packed pizza that stays true to the 21 Day Fix plan.
Prepare the Cauliflower Crust Mixture
Start by pulsing the 12 oz fresh cauliflower in a food processor until you get a rice-like texture. I like to work in batches if needed to avoid over-processing. Transfer the riced cauliflower to a clean kitchen towel and squeeze out as much moisture as possible—this is crucial for a crispy crust. The drier the mixture, the better it will bake.
In a large bowl, whisk together the 4 whole large egg whites until they form soft peaks. Add the 1.5 cups almond flour, 0.5 tsp baking powder, 0.5 tsp salt, 0.25 tsp black pepper, and 0.5 tsp Italian seasoning. Gently fold in the squeezed cauliflower until everything is evenly combined. The mixture should hold together when pressed but still be workable—if it’s too dry, add a splash of water.
Shape and Pre-Bake the Crust
Preheat your oven to 425°F and line a baking sheet with parchment paper. Transfer the crust mixture to the prepared sheet and spread it into a 12-inch round (about ¼-inch thick). Use your hands to press it evenly, creating a slight edge around the perimeter for that classic pizza look. This thickness ensures a crispy crust without burning.
Bake the crust for 15-18 minutes until the edges are golden brown and the center feels firm to the touch. You’re aiming for a sturdy base that can support toppings without collapsing. Let it cool for 5 minutes before adding toppings—this prevents a soggy crust when the sauce goes on.
Assemble the Pizza with Protein-Packed Toppings
Spread the 0.5 cup light tomato sauce evenly over the cooled crust, leaving a ¼-inch border for the crust to stay crispy. Sprinkle 1 cup shredded low-fat mozzarella cheese over the sauce, then layer the 1 cup chopped fresh spinach and 0.5 cup diced red bell pepper on top. Finish with the 2 minced garlic cloves mixed into the sauce for extra flavor.
Here’s the thing—don’t overload the pizza. The crust needs room to crisp up, and too many toppings can make it soggy. I like to keep it simple with these veggies and cheese for maximum protein and flavor without the guilt. The spinach wilts slightly during baking, so don’t worry if it looks abundant now.
Bake Until Cheese is Bubbly and Golden
Return the pizza to the oven and bake for 10-12 minutes until the cheese is bubbly and golden brown and the crust edges are deep golden. The cheese should pull away from the edges slightly, and the crust should sound hollow when tapped. If the crust starts browning too quickly, tent it loosely with foil to prevent burning.
This is where patience pays off—resist the urge to peek! Every time you open the oven, you risk losing heat and steam, which can make the crust soggy. The 10-12 minutes is your target, but watch for those visual cues: golden cheese and a crispy crust mean it’s ready.
Add Finishing Touches and Serve
Remove the pizza from the oven and let it rest for 2-3 minutes before slicing. This resting time allows the cheese to set slightly and makes it easier to cut clean slices. Drizzle with a little extra light tomato sauce or a sprinkle of Italian seasoning if you want to add more flavor.
Slice into 4 equal servings and enjoy while warm. The crust should be crispy on the outside with a tender interior, and the toppings should be perfectly melted and flavorful. This pizza delivers all the satisfaction of classic pizza with a fraction of the carbs—crispy, cheesy, and packed with veggies!
Pro Tips For Making 21 Day Fix Pizza
- Prep Cauliflower Like Rice: DESCRIPTION: Chop it into tiny grains—no bigger than a pea—before cooking. I learned this the hard way: larger pieces turn to mush instead of crisping up like rice. Use a food processor if you’re impatient (just pulse, don’t blend).
- Whip Egg Whites Fast: DESCRIPTION: Beat them cold—straight from the fridge—and use a clean, dry bowl. Warm egg whites resist whipping, and grease ruins their volume. Skip the mixer? Use a hand whisk for 2 minutes—you’ll get stiff peaks either way.
- Press the Dough Hard: DESCRIPTION: Roll it thin but don’t stress perfection—this isn’t a pie crust. Press it into the pan with your fingers until it’s uniformly flat. Thick spots burn; thin spots get soggy. A ¼-inch thickness works every time.
- Cheese Last, Heat First: DESCRIPTION: Spread sauce, add toppings, then sprinkle cheese in the last 2 minutes of baking. Low-fat mozzarella dries out fast—cover with foil if your oven runs hot. The cheese should melt but not turn rubbery.
Troubleshooting this dish
Crust Too Soggy
If your crust ends up soggy, it’s usually from excess moisture in the cauliflower or steam from toppings. First, squeeze the riced cauliflower extra dry—I use a clean kitchen towel and press hard to wring out every drop.
Also, pre-bake the crust longer (18-20 minutes) until it’s fully firm before adding toppings. For extra insurance, let the crust cool 10 minutes before assembling. 💧
Toppings Not Melting
Cheese refusing to melt? Your oven might not be hot enough or the cheese could be too cold. Preheat your oven to 425°F and let toppings sit at room temperature for 10 minutes before assembling.
For extra melt, sprinkle a light mist of water over the cheese before baking—it creates steam that helps the cheese soften. 🧀
Crust Not Crispy
A soft crust usually means the mixture wasn’t dry enough or didn’t bake long enough. Next time, add 1 extra tablespoon of almond flour to the mix for structure, and bake the pre-baked crust 2-3 minutes longer until golden.
For extra crispiness, broil for 1-2 minutes at the end of baking—just watch closely to avoid burning. 🔥
Sauce Too Watery
If your tomato sauce spreads too thin, it’s likely because it’s too thin to begin with. Simmer your sauce on the stove for 5-10 minutes to reduce it before spreading.
For a thicker base, mix 1 teaspoon cornstarch with 1 tablespoon water, stir into the sauce, and cook until it thickens. Rao’s no-sugar-added sauce works great, but any low-sugar marinara will do. 🍅
Pizza Sticking to Pan
Parchment paper is your best friend here, but if the crust still sticks, it’s likely because the oven isn’t hot enough or the crust wasn’t fully pre-baked. Next time, preheat your oven for 15 minutes and ensure the crust is fully firm before adding toppings.
If it still sticks, use non-stick spray on the parchment paper before shaping the crust. 🍳
Uneven Baking
Hot spots in your oven can cause uneven browning. Rotate the pizza pan halfway through baking to ensure even cooking. If your oven runs hot, tent the pizza with foil for the last 5 minutes to prevent over-browning.
For extra evenness, bake on the middle rack where heat is most consistent. 🌡️

Frequently asked questions
Can I use regular flour instead of almond flour for the crust?
Not for this recipe—almond flour keeps it low-carb and fits the 21 Day Fix guidelines. If you must substitute, try 1 cup oat fiber (blended) mixed with ½ cup almond flour for structure, but the texture will be denser. The crust relies on almond flour for that crispy, airy quality.
How do I adjust the recipe for a smaller or larger pizza?
For a 8-inch pizza, reduce all ingredients by 50% (use 6 oz cauliflower, 2 egg whites, etc.). For a 14-inch pizza, increase by 75% (keep proportions identical). The key is maintaining the ¼-inch thickness—thicker crusts need longer baking times. Always pre-bake the crust until firm!
What are the best 21 Day Fix-friendly toppings besides veggies and cheese?
Try low-fat turkey pepperoni, sautéed mushrooms, or diced chicken breast for extra protein. For veggie lovers, add sun-dried tomatoes (no oil added) or roasted red peppers. Just watch your container points—cheese and meat add up fast!
Can I make this pizza ahead of time?
Yes! Assemble the pizza (without baking) and refrigerate for up to 24 hours. Bake straight from cold, adding 2-3 extra minutes to the total time. For freezing, bake the crust only, then freeze with toppings in a sealed bag. Thaw overnight in the fridge before baking as directed.
Why does the crust crack during baking?
Cracking usually means the crust mixture was too dry or the oven temperature fluctuated. Add 1 tablespoon water if the dough feels brittle, and ensure your oven is fully preheated. For extra stability, press the crust edges slightly thicker (⅛-inch) before pre-baking.
