PROBLEM TO BE SOLVED: To provide a soybean paste-containing seasoning for freeze-dried foods, which solves the problem of separation of butter and soybean paste into two layers after restoration, capable of sufficiently imparting a fragrant roast flavor in parallel and a freeze-dried foods using the same.SOLUTION: Butter is first heated, and soybean paste is then added thereto to be heated and mixed, so that a soybean paste-containing seasoning is manufactured for use in freeze-dried foods. The soybean paste-containing seasoning alone or in combination with other food materials is freeze-dried, so that a freeze-dried food is manufactured. The soybean paste-containing seasoning has a blending ratio of butter to soybean paste of preferably 25 wt.% or less. The freeze-dried food manufactured using the soybean paste-containing seasoning allows the butter (oil content) to be entirely dispersed in a droplet form when poured with hot water for restoration. Consequently the problem of floating of butter on the surface due to separation of butter and soybean paste into two layers can be solved, and a fragrant roast flavor can be sufficiently imparted in parallel.
