Ingredients for brown rice diced tomatoes
Mediterranean pantry staples meet one-pot simplicity for this aromatic brown rice dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Long-Grain Brown Rice 🌾 | 1 cup | Uncooked, rinsed thoroughly |
| Diced Tomatoes (Canned) 🍅 | 15 oz | San Marzano preferred, undrained |
| Chicken Broth 💧 | 2 cups | Low-sodium preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For sautéing aromatics |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Fresh Parsley 🌿 | ¼ cup | Chopped, stems removed |
| Dried Oregano 🍃 | 1 tsp | Mediterranean blend preferred |
| Ground Cumin 🌿 | ½ tsp | Toasted for depth |
| Bay Leaf 🍃 | 1 whole | Removed before serving |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The San Marzano canned tomatoes make all the difference here—their sweet, meaty texture and low acidity create a rich base. Trader Joe's or Whole Foods carry them, or look for the label at any well-stocked grocery store. If you can't find them, Muir Glen is a solid second choice. Fresh tomatoes work in a pinch, but their high water content means you'll need to add extra broth. The brown rice should be long-grain for that nutty texture—Lundberg Family Farms is my go-to brand, but any organic or high-quality label works. Rinse it thoroughly before cooking to remove excess starch, which prevents the grains from clumping.
No San Marzano tomatoes? Crushed tomatoes in a 28-ounce can work at double the amount (28 oz instead of 15 oz), but you'll need to reduce the broth to 1.5 cups to balance the liquid ratio. Fresh parsley wilting? Dried parsley at one-third the amount keeps the flavor, though it lacks the bright freshness. The chicken broth can be swapped for vegetable broth for a vegetarian version, but the depth of flavor differs slightly. For extra richness, add 1 tbsp of tomato paste along with the fresh tomatoes—it intensifies the umami without overpowering. The bay leaf is non-negotiable for that subtle herbal note, but remove it before serving.
This dish reheats beautifully—honestly tastes better the next day as the flavors meld. Store leftovers in an airtight container in the fridge for up to 5 days, or freeze portions for 3 months. For meal prep, cook a double batch and portion into containers. The rice stays firm when reheated if you stir in 1 tbsp of water or broth before microwaving. The lemon juice at the end is optional but brightens the dish—add it fresh after reheating if you prefer. Garnish with extra parsley or a drizzle of extra-virgin olive oil for restaurant-quality presentation.
Why You'll Love This Recipe

Step-by-step instructions for one-pot Mediterranean brown rice
Here's the precise method for creating restaurant-quality brown rice with vibrant tomato flavors.
Sauté Aromatics in Olive Oil
Heat the 2 tablespoons extra-virgin olive oil in a medium saucepan over medium heat until shimmering. Add the diced yellow onion and cook for 4-5 minutes until softened and translucent. This foundational step develops the base flavor—don't rush it.
Add the 3 minced garlic cloves and cook for another 30 seconds until fragrant. You'll smell the garlic release its sweet aroma—this is when the flavors start to meld. Immediately add the 1 teaspoon dried oregano and ½ teaspoon ground cumin, stirring for 10 seconds to toast the spices slightly. The spices should be warm but not burning—this prevents bitterness in your dish.
Add Rice and Tomatoes
Increase heat to medium-high and add the 1 cup long-grain brown rice, stirring to coat the grains evenly with the aromatic oil. Cook for 1 minute until the rice is lightly toasted and smells nutty. This step enhances the rice's natural flavor and prevents mushiness.
Pour in the 15 ounces diced tomatoes (undrained), including the juices. Stir well to combine, then add the 2 cups chicken broth, 1 whole bay leaf, 1 teaspoon salt, and ½ teaspoon black pepper. Bring to a gentle boil, then immediately reduce heat to low. The liquid should barely bubble at the edges—this maintains even cooking.
Simmer Until Rice is Tender
Cover the saucepan with a tight-fitting lid and simmer for 40-45 minutes without stirring. The rice needs undisturbed cooking to develop its characteristic chewiness. Check the liquid level after 20 minutes—if it's significantly reduced, add ¼ cup hot water to maintain moisture.
After 45 minutes, the rice should be tender but still have a slight bite. If it's not quite done, continue cooking for another 5 minutes. The rice is ready when it's fork-tender but still holds its shape. This texture is crucial for Mediterranean dishes—too mushy and you lose the integrity of the grain.
Finish with Lemon and Fresh Herbs
Remove the saucepan from heat and discard the bay leaf. Stir in the 1 tablespoon freshly squeezed lemon juice and ¼ cup chopped fresh parsley. The acidity brightens the dish while the parsley adds freshness. Let the mixture sit covered for 5 minutes to allow the flavors to meld completely.
Taste and adjust seasoning if needed—you may want to add a pinch more salt or a squeeze of lemon. The final dish should balance the earthy rice with the bright tomato and citrus notes. Serve immediately while the rice is warm, or store covered in the refrigerator for up to 3 days for a quick meal.
Pro Tips For Making Brown Rice Diced Tomatoes
- Toast the Onions First: Sauté the diced yellow onion in olive oil over medium-high heat until the edges turn golden—about 5-6 minutes. This step deepens the flavor way more than just cooking them through, and it prevents that raw onion taste from lingering in your dish. (Yes, even if you’re impatient like me.)
- Rinse the Rice Twice: Give that brown rice a quick rinse in a fine-mesh strainer before cooking—twice, even if it feels like overkill. Unrinsed rice releases excess starch, which can turn your dish gummy later. I learned this the hard way after making mushy rice for three straight dinners.
- Simmer, Don’t Boil: Once the rice and broth are combined, drop the heat to low and keep it at a gentle simmer—tiny bubbles, not a rolling boil. Boiling can turn brown rice mushy and scatter it all over the pot. My grandmother swore by this, and she was right: patience here makes all the difference.
- Drain and Refresh Tomatoes: After opening the canned diced tomatoes, drain most of the liquid (save a little for broth if needed) and give them a quick rinse under cold water. This cuts down on excess acidity and keeps the dish from tasting canned. Sounds weird, but it works—your rice will thank you.
Storing and reheating your leftovers
Refrigerator Storage
Let your brown rice and tomato mixture cool to room temperature for no more than 2 hours before transferring to an airtight glass container—I love using Pyrex with snap-on lids for easy stacking.
Store at 40°F or below for up to 5 days, though the flavors actually deepen overnight as the spices meld. The rice maintains its texture beautifully when refrigerated properly. 🌡️
Freezer-Friendly Tips
For longer storage, portion the cooked rice into quart-sized freezer bags (leave 1 inch headspace for expansion) or glass meal prep containers. Freeze for up to 3 months—the lemon juice and herbs stay vibrant when frozen this way.
Thaw overnight in the fridge for best results, or microwave for 2-3 minutes on defrost before reheating. 🧊
Stovetop Reheating
My preferred method is stovetop reheating—it preserves texture better than microwaving. Add 2 tablespoons water or broth to the pan, cover, and heat over medium-low heat for 8-10 minutes, stirring occasionally.
The extra moisture prevents drying out. Taste and adjust seasoning—reheated rice often needs a pinch more salt or a squeeze of lemon. 🔥
Microwave Revival
For quick meals, transfer a portion to a microwave-safe dish, cover loosely with a damp paper towel, and heat on 50% power for 3-4 minutes. Stir halfway through to distribute heat evenly.
If the rice looks dry, add 1 tablespoon broth and microwave another 30 seconds. The damp towel keeps steam trapped for even warming. ✨
Meal Prep Strategy
Double the recipe and store components separately for flexible meals. Keep the rice in one container and tomatoes/spices in another—this lets you mix and match with proteins like grilled chicken or chickpeas.
Reheat rice alone for 2 minutes, then combine with warmed proteins. The flavors stay bright when prepped this way. 📅
Garnish Before Serving
Always finish with fresh garnishes after reheating. A sprinkle of chopped parsley or a drizzle of extra-virgin olive oil elevates the dish. For extra brightness, add ½ teaspoon lemon zest or a few Kalama red pepper flakes for heat. These final touches make reheated rice taste restaurant-fresh. 🌿

Frequently asked questions
Can I use fresh tomatoes instead of canned diced tomatoes?
Fresh tomatoes work, but you'll need to adjust the liquid ratio. Use 4-5 medium tomatoes (about 1.5 cups diced) and reduce the broth to 1.5 cups to prevent a watery texture. Fresh tomatoes release more juice as they cook, so monitor the liquid level closely. For best results, roast or sauté the tomatoes first to concentrate their flavor before adding to the rice.
How do I make this recipe vegetarian?
Swap the chicken broth for vegetable broth and add 1 can (15 oz) white beans or 1 cup cooked chickpeas for protein. For extra depth, stir in 1 tbsp tomato paste with the spices. The dish will have a heartier texture and still maintain its Mediterranean profile.
Why does my brown rice turn mushy?
Mushy rice usually means too much liquid or stirring too often. Always use 2 cups broth for 1 cup uncooked rice and check after 20 minutes—add only ¼ cup water if needed. Never stir while cooking; the rice needs undisturbed simmering. If it's still mushy, spread it on a baking sheet to dry slightly before serving.
Can I cook this in an Instant Pot?
Yes! Sauté the aromatics as directed, then add all ingredients except lemon juice. Seal the lid and cook on high pressure for 22 minutes, then quick-release. Stir in lemon juice and parsley at the end. The pressure cooker reduces cooking time while keeping the rice perfectly tender.
What's the best way to serve this dish?
This versatile rice pairs beautifully with grilled proteins like chicken or shrimp, or use it as a base for grain bowls. Top with avocado, feta cheese, and cucumber for a Mediterranean-inspired salad. For extra flair, serve with warm pita bread and a side of tzatziki. The dish also reheats wonderfully for meal prep!
