Four bowls · warm or chilled
Lemon-Dijon dressing gives these tuna white bean rice bowls without mayo a fresh finish without a creamy sauce. Tuna and cannellini beans add substance, cucumber and red onion supply crunch, and cooked rice forms the base. Keep the cool topping separate from rice you plan to reheat, then combine the two just before eating.
Use freshly cooked rice, a ready-to-heat rice pouch prepared according to its instructions, or properly chilled leftover rice. Old rice that has spent too long on the counter cannot be made safe simply by heating it again. Keep the rice and cold topping separate until serving if making lunches ahead.

Tuna White Bean Rice Bowls Without Mayo
Ingredients
- 3 cups cooked rice, made from about 1 cup dry rice according to the package, or equivalent ready-to-heat rice
- Two 5-ounce cans tuna, drained
- One 15-ounce can cannellini beans, drained and rinsed
- 1 cup diced cucumber
- 2 tablespoons finely chopped red onion
- 2 tablespoons olive oil
- 1 1/2 tablespoons lemon juice
- 1 teaspoon Dijon mustard
- 1/8 teaspoon fine salt, plus more to taste
- 1/4 teaspoon black pepper
- 2 tablespoons chopped parsley, optional
Method
- Prepare rice following its package directions. Keep freshly cooked rice hot until serving. If using chilled leftovers, reheat the portion you need to 165°F, stirring or rotating for even heating.
- While rice cooks, drain tuna thoroughly and flake it with a fork. Rinse and drain the beans. Dice cucumber and chop onion.
- Whisk olive oil, lemon juice, mustard, salt, and pepper in the mixing bowl. Add beans, cucumber, and onion, then fold until coated.
- Add tuna and optional parsley. Fold gently so some larger tuna flakes remain. Taste with a spoonful of rice before adjusting salt or lemon.
- Divide hot rice among four bowls and spoon the topping over it. Serve promptly. For a cold version, use properly chilled rice and keep the assembled bowls refrigerated until eating.
Measure the rice after cooking
The target is 3 cups cooked rice for four bowls, or about ¾ cup per bowl. The estimate of 1 cup dry rice varies with the grain and package directions. Rice pouches also vary, so measure their prepared contents.
Divide the rice first, then spoon the tuna, beans, and cucumber evenly between bowls. Distribute the remaining dressing at the end. Pack the topping separately from rice that will be reheated, and count storage time from the oldest prepared ingredient.
Choose and handle the ingredients
Water-packed tuna keeps the topping light and lets the lemon dressing stand out. Oil-packed tuna works too; drain it well, then taste before adding all the dressing oil. Start with the small amount of salt listed, since canned tuna can be quite salty. Use only cans in good condition and follow the package storage instructions.
Cannellini beans give the bowl a soft, creamy bite. Rinse off the canning liquid so it does not thin the dressing. Cucumber adds crunch; if yours has large watery seeds, scoop out the seedy center before dicing. Finely chopped onion spreads more evenly and is easier to eat than large raw chunks.
Rice choices and substitutions
White rice gives a relatively quick base. Brown rice works but usually takes longer, so its package timing replaces the estimate above. A rice pouch is useful when you need a smaller batch. For guidance on grain types, see types of rice and how to cook them.
Great northern beans can replace cannellini beans. Swap parsley for dill, or leave the herbs out. To make the topping without mustard, omit it and whisk the lemon and oil again just before combining. Add sliced radishes instead of some cucumber for extra crunch. For another canned-tuna dinner, see stovetop tuna noodle casserole without canned soup.
Troubleshooting the bowls
Dry rice: when reheating, add a small splash of water and cover according to your appliance instructions.
Watery topping: drain beans and tuna more thoroughly and remove watery cucumber seeds.
Strong onion: rinse the chopped onion in cold water, drain, and use a smaller amount.
Sharp dressing: taste it with beans and rice before changing it; add a teaspoon of oil if still too acidic.
Beans falling apart: slide a broad spoon under the mixture and turn it over gently. A few broken beans are fine; repeated stirring turns the topping into a mash.
Make ahead and safe storage
For planned leftovers, put rice and topping in separate shallow containers and refrigerate promptly within 2 hours, or 1 hour if temperatures exceed 90°F. Do not leave a large pot of rice on the counter to cool completely. Keep refrigerated food at 40°F or below and use it within 3–4 days, counting from the earliest cooking or preparation date. These handling limits follow USDA leftovers guidance.
Reheat only the rice to 165°F, then add the cold topping and eat promptly. You can also eat the entire bowl cold if it has been handled safely. Pack cold bowls in an insulated bag with an ice pack. Freezing assembled bowls is not recommended for quality because cucumber becomes watery; freeze rice separately if needed.
