Place the paneer in a bowl and toss with the ginger, garlic, coriander, garam masala, cumin, and salt.: As you mix these aromatics with the paneer , inhale the immediate lift of warm spices and sharp ginger. The texture of the paneer will feel cool and slightly springy, and the spices will begin to cling to the surface. This early contact helps the flavors penetrate the outer layer. One common mistake is under tossing, leaving some pieces unevenly coated, so be thorough and use a large bowl to get every cube well covered.
Add the 5 tablespoons of yogurt and stir until the paneer pieces are evenly coated. Let marinate at room temperature for 20 minutes or refrigerate and marinate overnight. Preheat the oven to 400°F.: Once the yogurt meets the spices, the mixture becomes creamy and glossy. The marinade should cling to the paneer like a light dressing, signaling that it will brown and caramelize nicely. Marinating at room temperature allows flavors to bloom quickly, while an overnight chill deepens the profile. Avoid leaving it out too long in warm conditions to prevent any off flavors. Preheating the oven ensures an immediate sizzle when the cubes go in.
Line a large baking sheet with aluminum foil and coat with nonstick spray. Arrange the paneer cubes on top in an even layer, discarding any excess marinade.: Setting the paneer cubes spaced evenly gives hot air access around each piece, helping edges turn lightly golden. The foil makes cleanup simple and the nonstick spray prevents sticking. If the cubes crowd, they steam instead of browning, so give them room. Removing excess marinade prevents charring or soggy bottoms, which can alter the desired texture.
Bake for 12 to 15 minutes, until the paneer is lightly golden at the edges. Remove from the oven and set aside.: During baking you will smell the spices toasting, and visually you want subtle golden edges rather than deep brown. That gentle color signals the exterior is set while the interior remains tender. Pulling them out too early means insufficient browning, while overbaking will make the pieces dry and rubbery. Letting them rest briefly off heat preserves juiciness while you prepare the masala.
While the paneer bakes, prepare the masala. Heat the coconut oil over medium-low in a large, sturdy skillet. Once hot, add the bell pepper, cauliflower, onion, ginger, garlic, salt, and pepper. Cook, stirring occasionally, for 1 minute, then increase the heat to medium and continue cooking until the vegetables are tender and the onion is translucent; about 12 to 15 minutes. Do not let the onion brown—if it starts to turn brown, reduce the heat and continue cooking until soft.: The oil should shimmer but not smoke, releasing a soft sizzle when the vegetables hit the pan. Initially you will get a bright, fresh aroma from the peppers and cauliflower, then as the onion softens the base will sweeten. The sound will shift from a sharp sizzle to a gentler simmer, and the vegetables will look glossy and slightly reduced. Browning the onion will push the flavor into caramel territory, changing the intended profile, so lower the heat if that happens. A typical slip is rushing to high heat which can char the outside while leaving raw centers.
Add the tomato paste, garam masala, turmeric, and cayenne. Cook and stir constantly for 30 seconds, until very fragrant.: When the concentrated tomato paste hits hot fat and spices, it transforms, releasing a deep, savory perfume. Stirring constantly prevents sticking and allows the spices to bloom evenly. You should feel warmth from the spices and smell a pronounced, toasted fragrance. Overcooking here can make the mixture bitter, so keep the interval short and attentive, using a wooden spoon to scrape any fond and incorporate those flavor bits.
Add crushed tomatoes and cook, stirring occasionally, until hot, about 2 minutes.: The skillet will fill with a bright tomato scent and the sauce will begin to thin, then thicken slightly as it heats. Visually, you want a uniform, glossy red base with tiny bubbles around the edges. This quick heating helps the flavors marry before the paneer and peas join. A common oversight is not deglazing or stirring enough, which can leave sticky bits that scorch, so keep an eye and stir a few times during this brief step.
Add the paneer and peas, and cook, stirring occasionally, until warmed through, about 2 minutes more.: Adding the warmed paneer and frozen peas brings a fresh pop of color and a cool contrast to the hot sauce that will rapidly equalize. You should hear a soft simmer and see the sauce cling to the paneer . The peas will plump and the paneer will absorb some sauce flavor. Avoid prolonged cooking here as the paneer can over softens and the peas can get mushy; a quick warm through preserves their textures.
Remove from heat and let cool for 1 minute. Stir in the 1/2 cup yogurt. Taste and add additional salt and pepper as desired. Sprinkle with cilantro and serve warm with naan bread or brown rice.: After removing from heat, stirring in the finishing yogurt creates a silky, mellow sauce, and the aroma will soften into a comforting, rounded bouquet. The texture becomes creamier immediately, and the bright cilantro at the end lifts the richness. Tasting here is crucial to balance salt and pepper. Avoid adding yogurt while the pan is still vigorously boiling, as sudden heat can make it split. Let it cool slightly to achieve a smooth finish.
