Quick Chicken Salad: Dani García's Secret Ingredient for Fast Dinners

The Michelin Chef's Hack for a 10-Minute Dinner

Dani García, a Michelin-starred chef, shared on Instagram a quick version of his Russian salad with chicken. The recipe is designed to solve a fast dinner while using leftover roast chicken. The star trick: using ketchup in the shredded chicken sauce, a common pantry ingredient that adds a sweet-and-sour kick without the need for complex sauces.

“"For the shredded chicken sauce, ketchup": the secret ingredient that elevates the dish.”

The original recipe includes boiled potato, shallot, spring onion, mayonnaise, and dill, but ketchup is the surprise element that enhances the flavor. According to the chef, this combination yields a creamy texture and a balanced flavor profile reminiscent of traditional Russian salad but with a modern twist. Moreover, using leftover roast chicken reduces food waste and saves cooking time.

The Science Behind the Salad

The combination of boiled potato, mayonnaise, and ketchup is more than just flavor. Potato provides complex carbohydrates for sustained energy, while mayonnaise (rich in healthy fats if made with olive oil) and ketchup (containing lycopene, an antioxidant) create an emulsion that enhances the absorption of fat-soluble nutrients. Lycopene from ketchup is better absorbed in the presence of fat, making this combination a nutritional win.

The chef uses shallot and spring onion, which contain sulfur compounds with anti-inflammatory and prebiotic properties. Dill adds flavonoids that may aid digestion. When potatoes are cooled after cooking, they form resistant starch, a type of fiber that feeds beneficial gut bacteria and improves glycemic control. This turns the salad into not just a quick meal but a metabolically smart one.

Recent research has shown that resistant starch can reduce post-meal blood sugar spikes and increase satiety. By preparing the salad in advance and eating it cold or at room temperature, you maximize this effect. Additionally, roast chicken provides high-quality protein, essential for muscle repair and enzyme and hormone production.

Key Findings

• Secret ingredient: Dani García uses ketchup for the shredded chicken sauce, adding sweetness and acidity without extra effort. Ketchup contains vinegar, which helps enhance flavors and balances the fat from mayonnaise.
• Preparation time: The recipe is completed in about 10 minutes, ideal for quick weekday dinners. This includes shredding the chicken and mixing ingredients, assuming the potatoes are already cooked.
• Leftover utilization: Leftover roast chicken is transformed into a new dish, reducing food waste. According to the FAO, roughly one-third of all food produced globally is lost or wasted, and recipes like this help combat that issue at home.
• Nutritional base: Boiled potato, when cooled, provides resistant starch, beneficial for gut health and blood sugar control. A 2022 study in Nutrients found that regular consumption of resistant starch improves gut microbiota diversity.
• Versatility: The recipe admits variations: you can substitute chicken with tuna, hard-boiled egg, or even tofu for a vegetarian version. Ketchup can be replaced with homemade tomato sauce or mustard for different flavor profiles.

Why It Matters

This recipe shows that leftover cooking can be fast and tasty. For those looking to optimize their diet without spending hours in the kitchen, the ketchup trick is a smart shortcut: it adds flavor without complex sauces. Moreover, using common and inexpensive ingredients makes this recipe accessible to any budget.

Roast chicken is an excellent source of lean protein, essential for muscle repair and satiety. Combined with potato and vegetables, it creates a balanced meal that can fit weight management or athletic performance diets. The inclusion of spring onion and shallot provides prebiotic fiber, which feeds beneficial gut bacteria and supports digestive health.

In the current context of 2026, where inflation and cost of living are growing concerns, recipes like this allow saving money by using leftovers and reducing purchases of processed ingredients. Additionally, the trend toward more sustainable and conscious eating makes dishes like Russian salad with chicken an option aligned with many consumers' values.

Your Protocol

1. 1Prepare the base in advance: Boil potatoes until tender, peel and dice. Let cool to enhance resistant starch. Mix with chopped shallot, spring onion, salt, and pepper to taste. You can prepare this base up to 2 days ahead and store in the fridge.
2. 2Prepare the chicken: Shred thigh and leg meat from roast chicken (about 200 g per person). Mix with 2 tablespoons of mayonnaise and 1 tablespoon of ketchup (adjust to taste). For a more intense flavor, add a pinch of smoked paprika or mustard.
3. 3Assemble the dish at serving time: Place the potato base on a plate or bowl, top with the chicken mixture, and garnish with fresh dill. Serve warm or cold, as preferred. For a more elegant presentation, use a ring mold.
4. 4Variations and adaptations: Substitute chicken with canned tuna (drained) for an even quicker version, or with chopped hard-boiled egg to boost protein. If you don't have dill, use fresh parsley or chives. For a vegan version, use smoked tofu crumbles and vegan mayonnaise.
5. 5Batch cooking tip: Cook double the potatoes and store half in the fridge for another recipe, like a Spanish tortilla or mashed potatoes. Roast chicken can also be frozen shredded for use in other preparations.

What To Watch Next

The use of ketchup in savory recipes is gaining popularity among chefs as a shortcut to umami and sweetness. Soon we may see more applications in traditional dishes, such as salad dressings, meat marinades, or even pasta sauces. Some chefs are already experimenting with homemade fermented ketchup, which adds probiotics.

Additionally, the "leftover cooking" trend aligns with sustainability and household economy, two key topics in 2026. Watch for new versions of classics with surprising ingredients, like Russian salad with beetroot or apple, which are appearing on social media. We may also see more recipes incorporating ketchup as a base for quick sauces, leveraging its versatility and low cost.

From a nutritional standpoint, research on resistant starch continues to advance. A 2025 study published in the Journal of Nutrition found that regular consumption of cooled potatoes improved insulin sensitivity in overweight adults. This suggests that dishes like Russian salad, eaten cold, could have additional metabolic health benefits.
