Ingredients

For the Soup Base

1 pound (450g) dried green split peas
200 g bacon (4 strips/4 ounces), cut into ¼-inch-thick slices
1 large onion, peeled and roughly chopped
2 garlic cloves, peeled and roughly diced
1 large carrot, peeled and roughly chopped
1 celery stalk, roughly chopped

For the Aromatics

2 bay leaves
3-4 sprigs dried thyme
1 .5 liters (6 cups) chicken stock

For Serving

Crème fraîche, for serving
Fresh herbs or micro-greens (optional garnish)
Salt and black pepper to taste

Instructions

Preparation

1 Prepare the split peas: One hour before cooking, place the split peas in a large bowl and cover with cold water. Stir gently so the split peas don’t stick together. Let soak for 1 hour – the water will become hazy as the peas release starch. Some pea skins may rise to the surface; discard these skins. Drain the peas and cover again with fresh water – notice how much clearer the water looks now. Stir again, discard any remaining skins at the surface, then drain and rinse under cold water. This double-rinse process removes excess starch and prevents the soup from becoming gluey. Set aside.
2 Set up your bacon station: Line a small plate with paper towels – this will be your bacon’s landing pad. In a large heavy-bottomed pot (a Dutch oven works perfectly), cook the bacon strips over medium heat, stirring frequently, until they’re beautifully browned and crispy, about 5 minutes. You’ll hear them sizzle and smell that irresistible bacon aroma. Transfer the bacon pieces to your prepared plate. Keep exactly 1 tablespoon (15ml) of that precious rendered bacon fat in the pot – this liquid gold will flavor your entire soup base.

Building the Flavor Base

3 Sauté the aromatics: Add the chopped onion and garlic to the pot with the reserved 1 tablespoon (15ml) bacon fat. Cook over medium heat, stirring occasionally, until the onion becomes translucent and fragrant, about 2 minutes. Don’t let the garlic brown – it should just become aromatic. Add the chopped carrot and celery, stir to coat with the bacon fat, then cover and cook for about 5 minutes until the vegetables have softened. This creates your flavor foundation – the French call this a mirepoix.
4 Combine and simmer: Add the prepared split peas, bay leaves, thyme sprigs, and chicken stock to the pot. Bring the mixture to a rolling boil over high heat, then immediately reduce the temperature to medium-low. Cover and let it simmer gently for 1 hour. The split peas should break down completely and become tender enough to mash with a spoon. You’ll know it’s ready when the peas have lost their shape entirely and the soup has thickened considerably.

Finishing Touches

5 Blend to perfection: Once the split peas are completely soft and cooked through, remove and discard the thyme sprigs and bay leaves. Now comes the transformation – purée the soup until completely smooth using either a food mill for the silkiest texture, an immersion blender for convenience, or a regular blender working in batches. If using a regular blender, be careful with the hot liquid and don’t overfill. The goal is a velvety, restaurant-quality consistency.
6 Season and serve: Taste and season with salt and black pepper as needed – remember, the bacon and stock already contribute saltiness. Ladle the hot soup into warmed bowls and top each serving with a generous dollop of crème fraîche and a sprinkle of the reserved crispy bacon. For extra elegance, quickly reheat the bacon in a pan over medium heat for 1 minute before serving. Garnish with fresh herbs or micro-greens if desired for a pop of color and freshness.

Recommended Equipment and Kitchen Tools

Essential Tools (for best results)

Heavy-bottomed pot or Dutch oven – This prevents the split peas from sticking and burning during the long simmer. The heavy bottom distributes heat evenly, which is crucial for this recipe’s success.
Immersion blender – Makes puréeing hot soup safe and convenient. No need to transfer hot liquid to a regular blender, reducing mess and burn risk.
Fine-mesh strainer – Perfect for rinsing the split peas and removing any debris. Also useful if you want an ultra-smooth soup texture.
Wooden spoon – Won’t scratch your pot and handles the thick consistency as the soup develops.

Helpful Upgrades

Kitchen scale – For precise measurement of the split peas and bacon, ensuring consistent results every time you make this recipe.
Food mill – The gold standard for achieving restaurant-quality smoothness. It removes any remaining pea skins while creating the silkiest possible texture.
Ladle with pouring spout – Makes serving much neater and more professional-looking, especially when adding the crème fraîche garnish.

Nice-to-Have Options

Microplane grater – Perfect for adding fresh nutmeg or lemon zest as finishing touches that elevate this classic soup.
Storage containers with tight lids – This soup keeps beautifully and actually improves in flavor overnight, making proper storage essential.

Pro Tips and Troubleshooting

Professional Techniques

Always soak your split peas for the full hour – this prevents them from breaking down unevenly and creating a gritty texture. When puréeing, work in batches if using a regular blender, and never fill more than halfway to prevent dangerous hot liquid explosions. For restaurant-quality smoothness, pass the puréed soup through a fine-mesh strainer after blending. The bacon fat is crucial – don’t skip it or substitute oil, as it provides irreplaceable flavor depth.

Common Mistakes and Solutions

If your soup becomes too thick, thin gradually with warm stock rather than water to maintain flavor intensity. Conversely, if it’s too thin, simmer uncovered for 10-15 minutes to concentrate. Avoid oversalting early – the bacon and stock contribute significant sodium, so season at the end. Never add the crème fraîche directly to the hot pot, as it will curdle; always dollop it onto individual servings.

Storage and Make-Ahead Strategy

This soup actually improves overnight as flavors meld. Store covered in the refrigerator for up to 5 days or freeze for 3 months. When reheating, add a splash of stock as the soup thickens considerably when cold. For entertaining, make it completely up to 2 days ahead – just reheat gently and prepare fresh bacon for garnish.

Scaling and Presentation

Double the recipe easily, but increase simmering time by 15 minutes for larger batches. For elegant presentation, drizzle the crème fraîche artistically and sprinkle bacon in a small mound rather than scattered. Warm your serving bowls for 30 seconds in the microwave – this simple step keeps the soup hot longer and shows professional attention to detail.

This classic French soup transforms humble ingredients into something truly special, proving that the best comfort food often comes from the simplest techniques executed with care and attention to detail.
