Step‑by‑Step Instructions for Spicy Tuna Bowls with Cauliflower Rice
Step 1: Prepare the Cauliflower Rice
Steam 2 to 3 cups of cauliflower rice in a pot or a microwave-safe bowl for about 5–6 minutes, until tender but not mushy. Once steamed, drizzle approximately 2 tablespoons of seasoned rice vinegar over the warm cauliflower rice and stir gently until well combined. This adds a delightful sushi-inspired flavor and sets the perfect base for your Spicy Tuna Bowls.
Step 2: Portion the Rice
Using a measuring cup, divide 1 cup of the seasoned cauliflower rice into each meal prep container—aiming for 4 containers for a week’s worth of lunches. Gently pack the rice down to create a stable layer that will support the creamy tuna mixture on top. This balance ensures each bite is a mix of flavors in your Spicy Tuna Bowls with Cauliflower Rice.
Step 3: Create the Spicy Mayo
In a medium-sized mixing bowl, combine 3/4 cup of mayonnaise, 1.5 tablespoons of sriracha sauce, and 1 teaspoon of toasted sesame oil. Whisk together until smooth and creamy, adjusting sriracha per your spice preference. The result should be a vibrant and flavorful spicy mayo that beautifully complements the tuna, enhancing the overall taste of your Spicy Tuna Bowls.
Step 4: Mix in the Tuna
Open and drain 3 cans of tuna, then add the tuna to the bowl with the spicy mayo. Use a fork to mix the tuna gently but thoroughly, ensuring every piece is coated in the spicy mayo. This step is crucial for achieving that creamy texture that makes these Spicy Tuna Bowls so satisfying.
Step 5: Assemble the Bowls
Evenly divide the spicy tuna mixture among the prepared containers, placing it right on top of the cauliflower rice. Use a spoon to spread it out, covering the rice completely. The contrasting colors of the creamy tuna against the fluffy cauliflower rice makes for a visually appealing meal prep option.
Step 6: Add Fresh Toppings
Slice 1 Persian cucumber into thin rounds and distribute the slices among each bowl, adding a refreshing crunch. Then sprinkle 1/2 tablespoon each of toasted black and white sesame seeds over the top of the tuna. Finish with sliced green scallions for a bright pop of color and flavor in your Spicy Tuna Bowls with Cauliflower Rice.
Step 7: Store and Serve
Seal each container with a lid and store in the refrigerator for up to 3 days. When ready to enjoy, consume cold or let it come to room temperature. This flexibility allows you to savor the flavors of the spicy tuna and cauliflower rice whenever it suits your busy schedule!
How to Store and Freeze Spicy Tuna Bowls
Fridge: Store your Spicy Tuna Bowls with Cauliflower Rice in airtight containers for up to 3 days to maintain freshness. Keep the cucumber slices separate until you’re ready to serve for that perfect crunch.
Freezer: While it’s best to enjoy these bowls fresh, you can freeze the spicy tuna mixture for up to 1 month. However, the texture of cauliflower rice may change, so avoid freezing the entire bowl.
Reheating: For best results, thaw the tuna mixture in the fridge overnight and enjoy cold or let it come to room temperature before serving. If reheating, do so gently in the microwave to prevent overcooking the tuna.
Serving Tip: When ready to eat, freshly add cucumber slices for a delightful crunch that elevates your meal!

Expert Tips for Spicy Tuna Bowls
-
Quality Tuna Matters: Use high-quality canned tuna for the best flavor. Tuna packed in oil can enhance richness, but be mindful of the calories.
-
Adjust Spice Levels: Start with less sriracha if you’re unsure about spice. You can always add more to the tuna mixture later to suit your taste.
-
Perfectly Steamed Cauliflower: Steam cauliflower rice just until tender. Overcooking can lead to mushiness, which won’t hold up well in your Spicy Tuna Bowls.
-
Cool Before Storing: Allow the tuna mixture to cool before storing in containers. This helps maintain freshness, keeping flavors vibrant for your meal prep.
-
Variations Galore: Don’t hesitate to experiment with different veggies or proteins. Shredded carrots or avocado also make delightful additions to your Spicy Tuna Bowls with Cauliflower Rice!
-
Storage Tips: Enjoy your bowls within three days for optimum freshness. Keep the cucumbers separate until ready to eat to maintain their crunch.
Spicy Tuna Bowls with Cauliflower Rice Recipe FAQs
How do I choose the right cauliflower for cauliflower rice?
Absolutely! When selecting cauliflower for your dish, look for heads that are firm and heavy with tightly packed florets. Avoid any that have dark spots or soft patches, as these can indicate spoilage. Fresh cauliflower can be found in stores (either whole or pre-riced), but I often opt for frozen options for convenience; just make sure to check the expiration date on the packaging.
How do I store Spicy Tuna Bowls in the fridge?
Storing your Spicy Tuna Bowls can be super easy! Place the bowls in airtight containers to lock in freshness and avoid odors from your fridge. Consume within 3 days for the best flavor and quality. If you want to keep your cucumbers crispy, store them separately and add them right before serving.
Can I freeze the Spicy Tuna mixture?
Very! To freeze the tuna mixture, first, scoop it into an airtight freezer-safe container or freezer bags. Make sure to label with the date; it can last for up to 1 month. However, I recommend not freezing the cauliflower rice, as the texture may become mushy once thawed. When you’re ready to enjoy, thaw the tuna in the fridge overnight and serve it over freshly made cauliflower rice.
What should I do if my cauliflower rice is too mushy?
Common troubleshooting! If your cauliflower rice turns out mushy, it may have been overcooked. For next time, steam it just until tender, around 5-6 minutes. If it’s already mushy, you can try draining any excess moisture using a fine mesh strainer and mix in some fresh, uncooked riced cauliflower to regain some texture.
Are there any dietary considerations for Spicy Tuna Bowls?
Absolutely! If you’re concerned about allergens, ensure that you select gluten-free mayonnaise and confirm that the canned tuna doesn’t contain any potential allergens. For those with seafood allergies, consider using chickpeas or cooked chicken as an alternative protein. Always check labels if you’re cooking for others—it’s better to play it safe!
Can I prepare these bowls in advance?
Very! These bowls are perfect for meal prep. You can make them on a Sunday and have delicious lunches ready all week! Just make sure to consume the bowls within 3 days for the freshest taste, and keep the cucumbers separate until you’re ready to eat for that crisp crunch.
