Roasted Strawberry Jam. Making strawberry jam in the oven may sound a bit strange but the intensely delicious result will quickly make you a convert to this unusual method. Just as delicious made with frozen strawberries too.

Making jam in the oven may sound a bit strange but the result will quickly make you a convert to this unusual method. The natural and added sugars slowly caramelize in the oven as the strawberries reduce and concentrate their delicious flavour.

This is the most intensely flavoured strawberry jam you will ever sample with a complimentary hint of caramel too. This particular jam was made from some half priced, very ripe strawberries in the produce clearance shelf at my local supermarket.

This jam idea is ideally suited to summer strawberry season when plenty of ripe berries are available too. It’s great for when you need to use up those quickly ripening berries in the fridge or when they are on sale at the local market.

Fresh strawberries are great when in season. I use frozen berries most of the time to make it a little more economical.

However, I make this jam all year round using frozen strawberries. Just this week, during a freezer clean out, I discovered a large unopened bag of them from Costco.

A few hours in the afternoon was all it took to turn those frozen strawberries into an economical, intensely flavoured jam.

This phenomenal jam gives your morning toast an instant upgrade but deserves to be centre stage in lots of delicious desserts too. It is amazing in a simple whipped cream “fool”, a delicious filling for turnovers or an outstanding topping for cheesecake.

Any dessert in which you would use strawberry preserves or jam will be made even better by adding this intensely flavourful jam instead.

July 2017 Update!

With strawberry season around once again this summer, I’ve been working away at even more strawberry recipes. But I cannot let the season go by without making this incredible jam.

Today, with a fresh batch made and a single sheet of frozen puff pastry needing to be put to good use, I threw together these delightful little pastries as an afternoon treat for Spouse and I. Oh my, they were so delectably buttery and flakey!

The intense strawberry jam married perfectly with the buttery pastry. Give them a try fro Sunday brunch or for when a friend drops over for an afternoon cuppa.

Yield: 2 cups jam (aprox.) 2 tsp per serving

Roasted Strawberry Jam

Prep Time: 10 minutes
Cook Time: 1 hour
Total Time: 1 hour 10 minutes

Roasted Strawberry Jam - Making strawberry jam in the oven may sound a bit strange but the intensely delicious result will quickly make you a convert to this unusual method.


  • 2 pounds very ripe strawberries, washed and quartered
  • 1 cup white sugar
  • 2 tsp vanilla extract


  1. Toss the strawberries, sugar and vanilla together in a glass baking dish.
  2. Roast in the oven at 350 degrees F stirring occasionally until the jam reduces and the juice almost completely boils off.
  3. Watch it closely toward the end of the cooking time because the sugars will be very concentrated and will more easily burn.


Cooking time will vary depending upon the water content of the strawberries and the depth of the baking dish. Allow up to 90 minutes for the jam to cook fully.

So when my local CBC radio station -London ON-asked folks to call in re strawberry jam making, I texted about your jam. I got a call, was asked questions & recorded, giving you credit for the recipe several times, & mentioning your roasted tomato jam, also.It was broadcasted the next day, in their inimitable way, making my rambling a bit interesting. But —did not include credit to you—-I did try! Still have to make it this year!

I used 2/3 c sugar— seems fine. Also, did one pound, 1/3 c sugar in an 8x8 glass baking dish — pleased with results.

Hiya. I made this recipe a couple of years ago. It makes incredible jam! However, now I'm wondering about adding rhubarb. Can you see a reason I shouldn't? Thanks in advance!
