Recipe Box, Mushroom & Spinach Tart with Garlic Rosemary Crust

This tart is a party in your mouth,

full of wonderful flavors and textures,

Fresh spinach, mushrooms, onions, roasted garlic, rosemary…


And optional blue cheese and bacon


This is not hard to make,

but it does require a little time in the kitchen

to get the ingredients prepped to assemble the tart

Totally worth the effort!

The crust is rubbed with roasted garlic* so get that started first

or make it a day or two before

*to roast garlic, cut off the top of the head to expose the cloves.  Place on a square of foil, drizzle with olive oil, season with salt and pepper, wrap foil to seal and roast in the oven at 400 degrees for 1 hour.  Can be kept in refrigerator for 1 week

Also if you want to use bacon, cook that before hand

I often roast a pan of bacon strips

and keep them in the refrigerator to use for salads, sandwiches etc.

Okay, let’s make the tart!

Unroll the dough rectangle, pinching the edge to form tart

Prick all over with a fork and cook for 6-8 minutes until firm

Spread partially cooked crust with roasted garlic

Sprinkle with rosemary

Saute the onions and set aside

Saute mushrooms until golden

Combine onions and mushrooms and hit them with a little cream

add cheese and stir until melted

Place spinach leaves in an even layer on tart crust

Sprinkle with bleu cheese*

*omit or substitute Parmesan or Gruyère

Top with Mushroom cream

Top with bacon {optional}

or use cooked chicken, ham, or prosciutto

Sprinkle with Parmesan

You can assemble this earlier in the day and refrigerate for baking later

Dig in!

    This does look pretty tasty, but would have to use the parmesan cheese as I just can’t develop a taste for bleu cheese. Will pin though. Jenna, I made your scones from yesterday’s post and my oh my, they were WONDERFUL!! My hubby and I each had three (oink, oink), lol, but I counted it as our lunch! Ha. I took two to my sister who was not feeling well and she enjoyed them with a nice hot
    cup of raspberry tea, she wants the recipe too! I have had scones only one time before and I wasn’t impressed as I thought they were very bland even with the clotted cream and or lemon curd.
    However, your recipe caught my eye with the good fruit mixed in and it did not disappoint! My dough was not overly sticky as my strawberries became kind of mushy as I diced them (they had been frozen, not fresh) and I think that gave a little more juice. I also loved the lemon glaze which gave it that extra zip. A keeper for sure. Many thanks, 😋.

    • Oh Cyndi I am so glad!! Thanks so much for letting me know, I love hearing feedback as everyone has slightly different tastes. I know you don’t like bleu cheese, but you can always substitute Gruyere, Manchego, sharp white cheddar, or use more Parm. Again, thanks so much, you’ve made my day 🙂

    This does sound very good and when social distancing stops, I’ll make this for appetizers with cocktails for a gathering of friends. Think I’ll sub Gruyère as I know some don’t care for bleu cheese. Pinning…thank you!
