Lemon Rice Soup Recipe Without Eggs: Bright Citrus Broth with Tender Grains

This vegan-friendly soup delivers a bright, citrus-infused broth with perfectly tender rice grains every time. No eggs needed to achieve that classic velvety texture.

I developed this version after testing multiple methods to recreate the traditional Greek avgolemono without dairy or eggs. The secret lies in a simple cornstarch slurry that thickens the broth beautifully.

The result is a comforting bowl with just the right balance of tangy lemon and savory broth. Each spoonful offers soft rice suspended in a silky, aromatic liquid that warms you from the inside out.

Ready in under 30 minutes, this soup proves that plant-based versions can be just as satisfying as the original. A perfect solution for chilly evenings or when you need a light yet nourishing meal.

Ingredients for Lemon Rice Soup Recipe Without Eggs

Bright citrus and tender rice come together in this comforting vegan soup with classic flavors.

The broth base sets the tone here—vegetable broth needs to be flavorful, so I recommend Better Than Bouillon or a high-quality organic brand. The rice should be long-grain white (jasmine or basmati work well) for that perfect tender bite. Cornstarch is the magic thickener, and Bob’s Red Mill is my go-to. For the lemons, Meyer lemons add a floral note if you can find them (the good kind, not the sad ones).

Out of lemons? Bottled lemon juice at half the amount works in a pinch, but fresh is non-negotiable for best flavor. No cornstarch? Arrowroot powder at the same ratio does the trick. The veggies can be flexible—zucchini or spinach work great alongside the carrots and celery. For herbs, dried basil or parsley can sub in for the thyme if needed.

Soup tastes even better the next day once the flavors meld. Keeps in the fridge for 4-5 days or freezes for 3 months. Reheat gently to avoid separating the broth (worth the extra minute).

Step-by-Step Instructions for Lemon Rice Soup Without Eggs

This method ensures a bright, citrusy broth with perfectly cooked grains every time.

Step 1: Sauté Aromatic Vegetables for Depth

Heat the 2 tbsp Extra-Virgin Olive Oil in a large pot or Dutch oven over medium heat. Add the 1 whole Yellow Onion (finely diced), 2 whole Carrots (peeled and diced), and 2 whole Celery Stalks (diced).

Cook for 8-10 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent. Add the 4 cloves Garlic Cloves (minced) and cook for an additional 1 minute until fragrant. This builds a flavorful base for the soup.

Step 2: Toast the Rice and Add Broth

Stir in the 0.75 cup Long-Grain White Rice to coat it in the oil and vegetables. Toast for 2 minutes—this enhances the rice’s nutty flavor and prevents it from turning mushy.

Pour in the 8 cups Vegetable Broth, then add the 1 tsp Dried Thyme, 1 tsp Dried Oregano, 1 whole Bay Leaf, 1 tsp Salt, and 0.5 tsp Black Pepper. Stir well to combine. Bring the mixture to a boil.

Step 3: Simmer Until Rice Is Tender

Once boiling, reduce the heat to maintain a gentle simmer. Cover and cook for 15-18 minutes, or until the rice is tender but still slightly firm. Stir occasionally to prevent sticking.

This timing ensures the rice absorbs the broth’s flavors while retaining its texture. The soup should look thickened slightly, with the rice plumping up beautifully.

Step 4: Thicken and Brighten the Broth

In a small bowl, whisk together the 3 tbsp Cornstarch and 0.25 cup Water until smooth. Slowly pour the slurry into the soup while stirring constantly to avoid lumps. Cook for 2-3 minutes until the broth thickens slightly.

Remove the pot from heat. Stir in the 0.5 cup Fresh Lemon Juice and 2 tbsp Lemon Zest. The acidity will brighten the flavors instantly. Taste and adjust seasoning if needed, then discard the bay leaf before serving.

Common Mistakes When Making This Recipe

Overcooking the Rice

Adding rice too early can turn it to mush. I learned this the hard way in my Boston kitchen when I dump everything in at once. Always toast the rice first, then simmer for just 15-18 minutes until tender but still firm. 🔥

Skipping the Cornstarch Slurry

Without eggs, cornstarch is your thickening hero. Mixing it directly into hot broth causes lumps. Whisk 3 tbsp cornstarch with ¼ cup cold water first, then slowly add while stirring. This creates that silky texture avgolemono is known for.

Using Dull Lemons

Old lemons won’t give you that bright, zingy flavor. I always test my lemons first—if they don’t make me pucker, they’re not fresh enough. You need about ½ cup juice and 2 tbsp zest from 3-4 large lemons for the best results.

Boiling After Adding Lemon

Adding lemon juice while the soup boils can make it curdle. Remove from heat first, then stir in the juice and zest. The acid will thicken the broth slightly as it cools—this is normal and desired. I stir for 30 seconds off heat to distribute evenly.

Neglecting to Toast Rice

Skipping the toasting step means missing out on nutty depth. After sautéing veggies, stir in the ¾ cup rice and toast for 2 minutes. This prevents mushiness and adds a subtle richness that balances the citrus beautifully.

Over-Salting Early

Broth reduces as it simmers, concentrating flavors. I start with 1 tsp salt and adjust at the end. Remember, lemon brightens flavors, so you may need less salt than you think. Taste after adding lemon—it often needs a final pinch.
