Check Updated code below, in particular this part: {type: Schema.Types.ObjectId, ref: ‘Ingredient’} var mongoose = require(‘mongoose’); var Schema = mongoose.Schema; var IngredientSchema = new Schema({ name: String }); module.exports = mongoose.model(‘Ingredient’, IngredientSchema); var mongoose = require(‘mongoose’); var Schema = mongoose.Schema; var RecipeSchema = new Schema({ name: String, ingredients:[ {type: Schema.Types.ObjectId, ref: ‘Ingredient’} ] }); module.exports …

In order to populate referenced subdocuments, you need to explicitly define the document collection to which the ID references to (like created_by: { type: Schema.Types.ObjectId, ref: ‘User’ }). Given this reference is defined and your schema is otherwise well defined as well, you can now just call populate as usual (e.g. populate(‘comments.created_by’)) Proof of concept …
