Jack in the Box Meal Combos

Jack in the Box occupies an interesting position: the menu is eclectic, but the core burger lineup actually delivers high protein numbers that compare well with any fast food chain.

The Bacon Ultimate Cheeseburger at 930 calories and 55g protein is the top of the lineup. The Ultimate Cheeseburger (840 cal, 47g protein) and Double Jack (830 cal, 46g protein) are close behind. These are substantial meals designed for larger calorie budgets. If your target is 900+ calories per meal, these hit the protein targets efficiently.

The Sourdough Breakfast Sandwich (810 cal, 40g protein) is one of the best breakfast options at any fast food chain. It uses thick sourdough bread, which adds texture and some carbs, with egg and sausage delivering 40g protein.

For the 600 to 700 calorie range, Jack in the Box gets trickier. Most of the high-protein items cluster above 800 calories. The Sausage Croissant (710 cal, 36g protein) or building with medium-sized burger options is the best path. The Grande Sausage Burrito (1,040 cal, 39g protein) is very calorie-heavy for the protein it delivers.

Tacos are the Jack in the Box wildcard. Regular Tacos at 170 calories and 6g protein are low-cost and low-calorie, but they're not going to anchor a high-protein meal. Treat them as supplemental additions rather than primary protein sources.

For sides, Jack in the Box's Egg Roll (210 to 570 cal, 7 to 21g protein) is an unusual but legitimate protein addition. The Side Salad at 50 cal is the lightest side. Hash Browns add 190 calories. Onion Rings at 220 calories are moderate.
