Stuffed Portabello Mushrooms

Stuffed Portabello Mushrooms could be an expensive dish, but I am going to share how I kept it affordable.

Often when I share tips for saving money on groceries, someone will mention that it is harder to find coupons on produce. And that is absolutely true. However, just because it is harder does not mean it is impossible. If you sign up to receive coupons from your local grocery stores, you will discover more produce coupons.

Another way that I save on produce is to use store coupons that can be used on any item on produce. Several of our local stores occasionally hand out $10.00 coupons (usually after you have purchased a certain amount of groceries) good on your next purchase. I always use those coupons on produce.  I use the pharmacy inside my local grocery store and after I have purchased a certain amount through the pharmacy, they issue me a coupon good for $10.00 off groceries. I reserve those coupons for produce too.

Often I use those $10.00 coupons to stretch my budget to include more organic produce, but occasionally I use them to buy something special. When I received a $10.00 coupon from Raley’s the week before Father’s Day, I decided to use it to buy portabello mushrooms to make stuffed mushrooms for my husband.I filled the mushrooms with spinach and onions from my garden and topped them with Raley’s Italian cheese blend because it was the lowest price cheese in the store. It ended up costing me about $3.50 cents to make 8 stuffed portabello mushrooms.

I reduced the sauce in a cream of spinach recipe to use in the stuffed mushrooms.

  • Place mushrooms gill side down and bake for 15 minutes.
  • While the mushrooms are baking, cook onions in butter until the onions are translucent.
  • Add spinach and spices to the onions and cook over medium flame until spinach is just wilted.
  • In a small bowl, mix milk and cornstarch together. Add to spinach and cook over medium flame until it the sauce begins to thicken.

I served the mushrooms as a side dish, but they would make excellent appetizers and are filling enough to work as a lunch with a side salad.

    We don’t get many (or very generous) coupons here in the UK either, but Portebello mushrooms are not as expensive here. I don’t know why. I’m glad though, because I can try your wonderful recipe – the flavours sound just fantastic!

    Hi Alea – these mushroom caps look wonderful! I love the idea of spinach in them, since DH so often insists upon meat. With him overseas, I can be as vegetarian as I want. What a tasty looking recipe. 🙂

    Nice recipe Alea, and good money saving tips too. Sadly, coupons are neither as available here in Canada nor as generous, but I do get coupons for gas purchases at our local big box store, and use those towards the cost of our produce.

Welcome. I'm Alea!

On Premeditated Leftovers I share simple recipes made with whole foods, practical shopping tips, time saving techniques, and meal planning strategies. I also share tips for minimizing food waste, so more of the food that is purchased ends up on the table.

While volunteering as a budget counselor, I realized that food is the element of most people’s budgets where they have the greatest control. I set out to develop low-cost recipes from scratch to prove it’s possible to create delicious meals on a limited budget. Eating well while spending less is about more than just creating recipes using inexpensive ingredients; it’s about creatively combining ingredients so you don’t feel deprived and are inspired to stick to your budget.
