Hello Claire. It is wonderful that you are taking on making tabbouleh. It is one of the freshest, most vibrant dishes you can make, and it is fantastic for meal prep once you understand the basic technique.
The most important detail to know about authentic Levantine tabbouleh is that it is primarily a parsley salad seasoned with a little bulgur, rather than a grain salad with parsley in it. In the traditional version, herbs make up the vast majority of the dish.
Here are the exact traditional ingredients:
1. Fresh flat-leaf parsley: 3 large bunches (stems removed)
2. Fresh spearmint: 1 small bunch (leaves only)
3. Fine bulgur wheat (grade #1): 3 tablespoons
4. Firm red tomatoes: 2 medium-sized
5. Green onions (scallions): 3 to 4 stalks, using both white and light green parts
6. Extra virgin olive oil: 1/3 cup
7. Fresh lemon juice: 1/3 cup (freshly squeezed makes a noticeable difference)
8. Fine sea salt: 1/2 teaspoon, or to taste
9. Ground allspice or Lebanese seven-spice: 1 small pinch (optional, but very traditional)
Step-by-step instructions:
Step 1: Wash and completely dry your herbs. This is the single most critical step in making good tabbouleh. Wash the parsley and mint thoroughly to remove any grit, then spin them in a salad spinner and lay them flat on clean kitchen towels until they are 100 percent dry. If you chop wet parsley, it will bruise, turn dark, and become soggy in your container.
Step 2: Prepare the bulgur. Measure out the fine bulgur into a small bowl. Rinse it lightly, drain it, and pour the fresh lemon juice directly over the raw bulgur. Let it sit for 15 to 20 minutes while you chop the vegetables. The fine bulgur will naturally soften by absorbing the lemon juice, so you do not need to cook it on the stove.
Step 3: Finely dice the tomatoes. Remove the excess watery seeds so the salad stays crisp, then finely dice the flesh into very small cubes. Place them in a bowl and season with a pinch of salt.
Step 4: Chop the herbs and onions. Using a very sharp chef's knife, gather the dried parsley into a tight bundle and slice it finely in a single, sharp pass. Avoid running the knife repeatedly over the herbs like a rocking blade, as that will crush them. Finely chop the mint leaves and slice the green onions into tiny rounds.
Step 5: Assemble and dress. In a large mixing bowl, gently toss the chopped parsley, mint, green onions, diced tomatoes, and the softened bulgur with its lemon juice. Pour in the extra virgin olive oil, add the remaining salt, and add the pinch of allspice. Toss gently with your hands or two spoons until evenly combined. Taste and adjust with a touch more lemon juice or salt if desired.
Meal Prep Tip: Since you mentioned meal prep, if you plan to eat this over 3 to 4 days, keep the dressed tomatoes and dressing separate from the chopped herbs, or toss everything together without the salt and add salt right before eating. Salt draws out moisture from the tomatoes and parsley, so dressing just before serving keeps it crisp and lively.
I hope this helps your meal prep journey. Please let me know if you have any questions along the way.
