Step‑by‑Step Instructions for Cheesy Broccoli Cauliflower Rice
Step 1: Heat the Skillet
Begin by heating 2 tablespoons of extra virgin olive oil in a large skillet over medium-high heat. Once the oil shimmers, indicating that it’s hot enough, prepare to add the vegetables. This initial step sets the stage for perfectly sautéed veggies, infusing them with a delightful flavor from the olive oil.
Step 2: Cook the Vegetables
Add 3 cups of riced cauliflower and 2 cups of riced broccoli to the skillet, seasoning generously with salt and pepper. Sauté everything together for 8-9 minutes, stirring occasionally, until the broccoli is bright green and the cauliflower is just tender. Remove the mixture from the skillet and set aside, allowing it to rest while you create the creamy sauce.
Step 3: Make the Cheese Sauce
In the same skillet, melt 2 tablespoons of butter over medium heat. Once melted, whisk in 1 cup of heavy whipping cream and 1 teaspoon of mustard powder, stirring continuously until the mixture begins to bubble gently. This process should take about 2-3 minutes, creating a luscious base for your Cheesy Broccoli Cauliflower Rice.
Step 4: Incorporate the Cheese
With the cream mixture bubbling, add 2 cups of shredded sharp cheddar cheese to the skillet. Stir confidently until the cheese is fully melted and the sauce is smooth, which should take an additional 2-3 minutes. This cheesy goodness will envelop the vegetables beautifully, transforming them into a rich dish.
Step 5: Combine and Serve
Return the sautéed riced cauliflower and broccoli back to the skillet with the cheese sauce. Mix well for 2-3 minutes on low heat, ensuring the vegetables are thoroughly heated and coated in the creamy sauce. Watch for the dish to become a vibrant mix of colors, promising an enticing flavor in every bite.

Make Ahead Options
These Cheesy Broccoli Cauliflower Rice are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can pre-cook the riced cauliflower and broccoli up to 24 hours in advance, mixing them with a bit of olive oil and seasoning before refrigerating them in an airtight container. The creamy cheese sauce can also be prepared up to 3 days ahead; just store it separately to maintain its silky texture. When you’re ready to serve, simply reheat the veggies and cheese sauce together in a skillet over low heat for about 5 minutes, ensuring everything is heated through and flavors meld beautifully. This way, you’ll be enjoying a comforting, homemade side dish in no time!

Cheesy Broccoli Cauliflower Rice Recipe FAQs
What is the best way to select fresh broccoli and cauliflower for this recipe?
Absolutely! When choosing fresh broccoli, look for vibrant green florets that are tightly packed. Avoid any with yellowing tips or dark spots. For cauliflower, a firm head with a creamy white color and no dark spots is ideal. If you see any dark areas or soft spots, choose another head.
How should I store Cheesy Broccoli Cauliflower Rice leftovers?
Store your leftovers in an airtight container in the fridge for up to 3-5 days. It’s best to let the dish cool completely before sealing to prevent condensation, which can make it soggy. When you’re ready to enjoy it again, simply reheat on the stove or in the microwave, adding a splash of cream to help restore its creamy texture.
Can I freeze Cheesy Broccoli Cauliflower Rice?
Certainly! To freeze, place the cooled dish in a freezer-safe container or divide it into portion-sized servings. It will keep well for up to 3 months. When you’re ready to eat, let it thaw in the refrigerator overnight. Reheat and add a splash of cream or milk for a deliciously creamy texture upon serving.
Why is my cheese sauce not melting smoothly?
Very! If your cheese sauce is clumping or not melting smoothly, it could be due to using pre-shredded cheese, which often contains anti-caking agents. For the best results, always shred cheese from a block just before adding to the sauce. Additionally, make sure your cream mixture is hot enough when you add the cheese to ensure a good melt.
Are there any dietary concerns to consider with this recipe?
Oh yes! This dish is naturally gluten-free and low-carb, making it perfect for keto diets. However, ensure that the cheese you use is gluten-free if you’re adhering to strict dietary restrictions. Keep in mind that while this dish is vegetable-based, people who are allergic to dairy should consider using a dairy-free cheese substitute, although this may change the recipe’s flavor and texture.
How can I enhance the nutritional value of Cheesy Broccoli Cauliflower Rice?
What a great question! To make it even healthier, consider adding protein sources like grilled chicken, crumbled turkey bacon, or chickpeas. You can also toss in additional vegetables like spinach or bell peppers for added nutrients. Just sauté them along with the cauliflower and broccoli for a complete meal packed with flavor and health benefits!
