1-Step 1: Crisp the Garlic Heat the vegetable oil in a large pan over medium heat. Add the sliced garlic cloves and cook them gently until they turn a beautiful golden brown. This usually takes about 2-3 minutes, but watch them closely because garlic can go from golden to burnt very quickly. You want them crispy and aromatic, not dark or bitter. Once golden, remove the garlic slices from the oil and set them aside on a paper towel. These crispy garlic pieces will become a delicious garnish that adds texture and intense garlic flavor to your finished dish. The oil is now infused with garlic essence, which will flavor everything else you cook.

2-Step 2: Caramelize the Onions Add the sliced onions to the same garlic-infused oil with a generous pinch of salt. The salt helps draw out moisture and speeds up the browning process. Cook the onions over medium heat for about 6-8 minutes, stirring occasionally, until they develop a deep golden brown color. You want your onions to turn a nice golden brown here. Don’t rush this step, as it really builds the flavor base for your curry and makes all the difference in the final dish. Once caramelized, remove about one-third of the onions and set them aside. These will be added back later for texture and visual appeal.

3-Step 3: Build the Aromatic Base With the remaining onions still in the pan, add the garlic paste and ginger paste. Cook these for about 30 seconds, stirring constantly. The raw smell should disappear, replaced by a fragrant, appetizing aroma. Be careful not to let the pastes stick or burn. Next, add all your dry spices: the chilli powder, paprika powder, cumin powder, and madras curry powder. Stir them into the onion mixture and cook for 1 minute. Add a small splash of water if the spices start to stick or look like they might burn. This step blooms the spices, releasing their essential oils and deepening their flavors.

4-Step 4: Create the Tomato Sauce Pour in the blended vine-ripened tomatoes and 150 ml of the chicken stock. Stir everything together, scraping up any bits from the bottom of the pan. Let this mixture simmer for 5 minutes, stirring occasionally to prevent sticking. The tomatoes will break down and meld with the spices, creating a rich, aromatic base. After simmering, remove the pan from heat and carefully blend the mixture until completely smooth. You can use an immersion blender directly in the pan or transfer to a regular blender. Return the smooth sauce to the pan.

5-Step 5: Finish the Curry Pour in the remaining 300 ml of chicken stock and add the whole green finger chillis. Bring everything to a gentle simmer and let it cook for another 5 minutes. The chillis will infuse the sauce with fresh heat and look beautiful in the finished dish. Add the reserved caramelized onions and most of the crispy garlic slices, holding back a small handful for garnish. Let everything cook together for 2 minutes so the flavors combine. Stir in the kasoori methi, crushing it slightly between your fingers as you add it to release its aroma. Finally, sprinkle in the garam masala and adjust salt to taste.

6-Step 6: Serve and Enjoy Transfer your Zesty Garlic Chilli Chicken to a serving dish and garnish with the reserved crispy garlic slices and freshly chopped coriander. Serve hot with steamed basmati rice, warm naan, or your favorite flatbread.
