Why You’ll Find This Delicious

• Hearty and satisfying thanks to fiber-rich beans and rice

Ingredients

• Sweet potatoes – Add natural sweetness and a creamy texture once baked; they balance the savory spices beautifully
• Black beans – Provide plant-based protein and a hearty, earthy base
• Canned diced tomatoes – Create moisture and a rich, slightly tangy backbone for the dish
• Onion – Brings depth and subtle sweetness as it softens in the oven
• Bell peppers – Add color, brightness, and a gentle sweetness
• Paprika (or smoked paprika) – The defining flavor; smoky paprika gives a deeper, more traditional Spanish-style profile
• Fresh garlic – Sharp, aromatic, and essential for layering flavor
• Garlic powder – Reinforces the garlic note and distributes evenly
• Onion powder – Adds a savory undertone that blends throughout the rice
• Salt – Enhances and balances all flavors
• Black pepper – Adds gentle heat and complexity
• Basmati or jasmine rice – Light, fragrant grains that cook perfectly in the oven
• Water – Absorbed by the rice to create a fluffy, cohesive dish

Equipment Needed

• 9×9-inch baking dish
• Aluminum foil
• Cutting board and knife
• Measuring cups and spoons
• Fork (for fluffing)

Prep for the Recipe

Cube the sweet potatoes into small, even pieces (about ½ to 1 inch) so they cook through at the same rate as the rice. Dice the onions and bell peppers, and mince or press the garlic finely so it distributes evenly throughout the dish.

Drain and rinse the black beans to remove excess sodium and improve flavor.

How to Make Sweet Potato Bean Bake Rice Bake

1. Preheat your oven to 375°F (190°C).
2. Add all ingredients directly into a 9×13 baking dish:
   • Sweet potatoes
   • Black beans
   • Diced tomatoes (with juices)
   • Onion and bell peppers
   • Garlic and spices
   • Rice
   • Water
3. Stir everything thoroughly in the dish so the rice is evenly distributed and submerged as much as possible.
4. Cover tightly with aluminum foil.
5. Bake for 35 minutes.
6. Remove from the oven and let it stand, covered, for 10 minutes.
7. Remove foil and fluff gently with a fork before serving.

Serving and Pairing Suggestions

This dish is satisfying on its own, but it also pairs beautifully with:

• A simple green salad with citrus vinaigrette
• Sliced avocado or guacamole for creaminess
• Fresh cilantro and a squeeze of lime for brightness
• Roasted vegetables or sautéed greens
• A dollop of vegan sour cream or cashew crema

Storing

Allow leftovers to cool completely before storing. Keep in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or on the stovetop with a splash of water to restore moisture.

This dish also freezes well for up to 2 months. Thaw overnight in the refrigerator before reheating.

Tips and Tricks

• Cut sweet potatoes small to ensure they cook fully in the same time as the rice
• Use smoked paprika for a deeper, more traditional flavor
• Stir well before baking so the rice cooks evenly
• Check moisture – if your oven runs hot, you can add an extra 2–3 tablespoons of water
• Let it rest after baking—this step helps the rice finish steaming and prevents mushiness

FAQ

Can I use brown rice instead of white rice?
Yes, but it will require more water and a longer baking time (about 15–20 minutes more).

Do I need to cook the rice first?
No—this is a true dump-and-bake recipe. The rice cooks in the oven with the liquid.

Can I make this oil-free?
It already is! This recipe uses no added oil.

What other beans can I use?
Pinto beans or kidney beans work well as substitutes.

Can I add extra vegetables?
Absolutely—zucchini, corn, or spinach are great additions.
