Decluttering will be a good start, and remove curtain.

Are you looking for a kitchen remodeling solution or a quick, easy solution?

The easiest permanent fix without replacing cabs would be to pull out the stove to match the depth of the corner...perhaps the whole run of lower cabinets if the space allows. Others have built basically a half wall to move cabinets out and use the resulting back "shelf" for out-in-the-open storage. Most of the examples I have seen were completely tiled or tile with a stone capping that made the "shelf."

This approach will not address easier access to the upper corner cabs, however.

get some 12 in bamboo laz susans across the back of the counter and use them for your oils/spices/etc. Clear the large items just sitting there. Leave the corner alone from a construction point of view until you do a complete remodel. I see a knife block..maybe get a good large cutting board and just leave it on this part of your counter as a regular prep spot. You have to just work with this anomaly...clean up the area so using it comes naturally.

Put the least used things in your kitchen in that corner cupboard. I like the idea of putting practical storage units in the corner such as lazy susan, knife block, container with cooking utensils.

Pulling the stove out at this point doesn't make sense as it crowds the sink area.

I thought this was kind of cool

Probably not much you can do unless you're prepared to do actual construction.

decluttering and removing a curtain will not make the corner sticking out go away.

do you have more counter space / cabinets to the left of the stove? if so, is it possible to move the stove to the left? that'd help if you can pull the stove out (and move left) to give room for working at stove and sink. maybe just put in cheap BB (Ikea) for now.

as for the deep corner, it'd be a good place for the mw on the diagonal - if you use one and are tall enough. the upper cabs will probably only be used for things you seldom use - unless you're tall. at 5', I sure couldn't reach them.

if you don't use the basement much, how about putting in a fire pole? of course, I have no idea how'd you get back up (without calling the fire dept)...

maybe a ladder would be a better idea...

makes ya wonder what whoever did it that way was thinking. I doubt it was anyone who cooked.

It would be really helpful if you posted the kitchen floor plan and whether you're just looking for bright ideas to make it more palatable or if you're really considering some level of remodeling.

need the whole kitchen lay-out to discuss this... it's very awkward... it think there are better ways to lay this kitchen out, it's just hard to tell from this one single picture. sketch would help too

Blfenton is right about crowding the stove...can the stove be switched with the cabinet that we cannot really see next to it? Just doing that would help.

upon looking at your photo: the dishwasher seems to be protruding......can it be pushed back under counter.....or are the counters not full depth.....or maybe this model dishwasher is extra deep ?? A dishwasher should be able to rest back under the counter overhang. Then without that obstruction, you could reverse your use and place drying rack to the left of sink in awkward corner and actually use the counter to the right of sink . Where you can't likely change the awkward corner until a remodel, you can potentially do something about the dishwasher to eliminate that obstacle, and go on and use that counter area..put the dishrack on the left.
