Portabella Mushroom Burgers with Provolone, Caramelized Onions, & Roasted Red Peppers

This is the last recipe that I made during summertime but hadn’t shared yet, and it’s appropriate that I waited to post it until today considering the high is 34°C (93F) here, with a humidex of over 40°C (104F) – it feels hotter today than most days we had during real “summer”!  Not that I’m complaining, because it’s lovely to get one more blast of heat before it likely cools down for good. And I’m ready for that too – football started this past weekend (go niners!), my sister went apple picking, and there was a chill in the air but still sunny skies, all of which got me pretty excited for fall!

And while burgers are usually seen more as summertime food, the earthy, smoky flavours in this particular burger make it great for this transition period into fall!

I’ve eaten portabella (or portobello, if that’s how you like to spell it) burgers a few times before but had never made one myself until now. Portabella mushrooms make a great vegetarian substitute for burgers because they have a meaty texture and earthy taste, but without the fat that usually comes along with meat burgers!

Plus mushrooms make a great canvas for piling on flavourful toppings. For my version, I decided to complement the smoky, savoury flavour of the mushrooms with caramelized onions and a little provolone cheese, which I then balanced out with sweet roasted red peppers and peppery fresh arugula.

Not only was this burger pretty healthful, but it was also packed with flavour – I devoured mine and then immediately scolded myself for not making portabella burgers earlier!

A few tips I learned along the way: 1) Marinating the mushrooms beforehand gives them extra flavour, as otherwise mushrooms on their own can be somewhat bland; 2) Be sure to spray or oil your grill/pan because the mushrooms can be somewhat sticky!; and 3) Mushrooms shrink as they cook and release moisture – I chose large buns based on their size pre-cooking, but as you can see, they didn’t fill the bun after cooking, so smaller buns would have been a better choice!

Don’t wait as long as I did to try these if you haven’t yet; and if you’re already a mushroom burger fan, feel free to share your own cooking tips or favourite recipes!

If you’re having as great as weather as we are here today, hope you get a chance to get outside and enjoy it!

Portabella Mushroom Burgers with Provolone, Caramelized Onions, & Roasted Red Peppers

Makes 2 burgers

Ingredients:

For the Mushrooms:

2 portabella mushrooms

2 tablespoons balsamic vinegar

1 tablespoon olive oil

Pinch each dried basil and oregano

1 clove garlic, minced

Salt & Pepper

For the Toppings:

1 red bell pepper

1 tablespoon olive oil, divided

1 large or 2 small yellow onions, peeled and sliced into half moons

Salt and pepper

Splash of balsamic vinegar

2 large slices of provolone cheese (enough to cover the two mushrooms)

2 handfuls of baby arugula

2 whole wheat hamburger buns

Directions:

Preheat oven to broil.

Remove stems of mushrooms and scrape out the gills, if desired.  Whisk together the vinegar, oil, basil, oregano, garlic, and a bit of salt and pepper in a small bowl.  Add mushrooms and marinade to a bowl, tossing mushrooms to coat well.  Leave to marinate for 20-30 minutes.

Rub red pepper with a teaspoon of olive oil (don’t use extra virgin olive oil as it has a lower smoke point.  Vegetable or canola oil would also work.)  Place on foil-lined baking sheet on the top rack of the oven.  Broil until dark blotches begin to appear on one side, then turn with tongs and repeat until all sides have black patches.  Amount of cooking time will vary depending on your oven and the size of your pepper; mine took around 15-20 minutes total.  When done, remove from oven and place in a bowl.  Cover tightly with saran wrap to let pepper steam (and loosen the skin) for about 15 minutes or until slightly cooled, then remove the skin, cut pepper in half, scrape out the seeds and membranes, and slice into strips.  

*Note: If you’re short on time, you can use storebought roasted red peppers in a jar.  I preferred to make my own to use less oil; it does take some time, but it can be done while you’re marinating/cooking the mushrooms and caramelizing the onions so everything finishes in roughly the same amount of time.

Meanwhile, heat 2 tablespoons of oil in a large non-stick skillet over medium heat.  Add sliced onions, stir to coat with oil, and season with salt and pepper.  Spread onions out evenly across the pan and let cook, stirring occasionally, until onions are soft and caramelized, about 25-30 minutes. Don’t stir the onions too often so they can brown, but don’t leave them alone long enough to burn or stick to the pan. Add a splash of balsamic vinegar about 20 minutes into cooking to deglaze the pan and darken the onions.  When done, set aside in a small bowl.

When mushrooms are done marinating, heat a grill or indoor grill pan over medium heat.  Brush grate with oil or spray grill pan to prevent sticking, then place mushrooms on grill with gill sides up first.  Grill for 5-7 minutes per side or until tender, brushing with the marinade a few times.  In last 2 minutes of cooking, add provolone cheese on top of each mushroom to melt.  If desired, toast buns on grill for 1-2 minutes as well.

Assemble burgers by topping the provolone mushrooms with the caramelized onions, roasted red peppers, and arugula on whole wheat buns.  Season with additional salt and pepper if desired.

Butternut Squash Lasagna with Smoky Marinara Sauce

I know I haven't been posting as often lately, but I've developed a seemingly never-ending cold that has resulted in my attempting to eat garlic and ginger for every meal to try to get rid of it (so far, no luck). I haven't felt like cooking nice meals that I won't even be able to taste, or baking treats for others that will probably just spread my germs to them.

Fortunately I still have a few recipes that I haven't shared with you guys yet, and this delicious lasagna is one of them. I actually made it back when I was testing recipes for my Canadian Thanksgiving Week because I thought a lasagna would make a great vegetarian Thanksgiving main dish. While I absolutely loved this dish, I ended up posting a roasted vegetable galette instead because I thought it was just slightly more appropriate for a Thanksgiving dish.

I've been waiting for a chance to post the lasagna recipe though, and now with American Thanksgiving coming up this week, along with lots of other opportunities for family gatherings in the coming months, I think now's the time to share this dish that is very worthy of taking center stage at your next family feast.

I've actually tried three different versions of butternut squash or pumpkin lasagna before, usually with some sort of white sauce, cheese, and sage, but they always seem to disappoint me because they end up being very one-dimensional in flavour. I was intrigued when I saw this recipe for butternut squash lasagna from Cooking Light, because it looked completely different from the other recipes I'd tried by combining squash with a smoky marinara sauce instead the more common white sauces I'd seen.

I'm so glad I gave this version a try because I now finally have a squash lasagna recipe with FLAVOUR! The smoky marinara sauce (which you must be sure to buy the fire-roasted tomatoes for) has such an interesting flavour that made it the star of the dish, while still complementing the squash nicely. The provolone cheese added to the smokiness of the dish, and the addition of three other cheeses (ricotta, goat cheese, and parmesan) created a wonderful combination of flavours that was so much more interesting than the more traditional but bland combination of mozzarella and ricotta. I used fresh lasagna noodles so the end product had a wonderful texture, but dried noodles would work just fine as well.

The only downside to this recipe is that it's a fair amount of work and contains a lot of ingredients, but I just poured myself a glass of wine and put on some good music to listen to, and I thought the whole process was really enjoyable! Your guests (both vegetarians and meat eaters) will love this impressive and delicious dish, and since it makes a ton, you'll hopefully be able to enjoy the leftovers all week!

Butternut Squash Lasagna with Smoky Marinara Sauce

Adapted from Cooking Light

Serves 12

Ingredients:

For the smoky marinara:

1 tablespoon olive oil

3 garlic cloves, minced

1/4 cup chopped fresh basil

2 tablespoons chopped fresh parsley

2 tablespoons chopped fresh or 2 teaspoons dried oregano

2 teaspoons balsamic vinegar

1/8 teaspoon salt

1/8 teaspoon pepper

1 (28-ounce) can crushed tomatoes, undrained

3 (14-ounce) cans diced fire-roasted tomatoes, undrained

For the lasagna:

1 tablespoon olive oil

3 cups chopped onion

3 cloves garlic, minced

10 cups fresh spinach

1 cup shredded sharp provolone cheese

1/2 cup chopped fresh flat-leaf parsley

1 teaspoon salt

1 teaspoon freshly ground black pepper

2 large eggs, whisked

1 and a half 15-oz cartons (22.5 oz total) reduced-fat ricotta cheese

1 (113g) log of goat cheese
1 large butternut squash

Smoky marinara sauce (from above)

6 eight-inch square sheets of fresh lasagna, or 12 oven-ready boxed lasagna noodles

1 cup (4 ounces) grated fresh Parmesan cheese

Directions:

Preheat oven to 400°F. Peel butternut squash, scoop out the seeds, and slice into thin pieces, about ¼ to ½-inch thick. Spread on a large baking sheet and toss with olive oil, salt, and pepper until evenly coated. Roast in the oven for 30-40 minutes, until soft, but not mushy. Remove from oven and set aside.

Meanwhile, prepare the smoky marinara sauce. Heat olive oil in a large saucepan over medium heat. Add garlic, basil, parsley, and oregano, and sauté 1 minute, stirring frequently. Stir in vinegar, salt, pepper, and the cans of tomatoes. Reduce heat and simmer for 10-20 minutes. Remove from heat.

Reduce oven temperature to 375°F. Spray a 9x13 glass baking dish with cooking spray.

Heat olive oil in a large saucepan over medium-high heat. Add onion and sauté 5 minutes, or until soft. Add garlic, and sauté for 1 minute, stirring frequently. Add the spinach and sauté for 1-2 minutes, or until spinach wilts. Transfer everything to a large bowl. Add the provolone, ricotta, goat cheese, parsley, salt, pepper, and eggs to the bowl and stir everything together until thoroughly combined.

To layer the lasagna:

1. Coat the bottom of the dish with 1/4 of the marinara sauce
2. Layer lasagna noodles on top of the sauce (2 of the fresh sheets, or 4 dry sheets)
3. Spread half of the cheese mixture on top of the noodles
4. Layer half of the roasted squash pieces over the cheese
5. Spread 1/4 of the marinara sauce over the squash
6. Layer more lasagna noodles over the marinara
7. Spread the other half of the cheese mixture over the noodles
8. Layer the other half of the squash over the cheese
9. Spread 1/4 of the marinara sauce over the squash
10. Layer the last of the noodles over the marinara
11. Spread the rest of the marinara sauce over the noodles
12. Sprinkle the parmesan cheese on top.

Cover with foil and bake at 375°F for one hour.

*Note: The original recipe called for the lasagna to be divided among two 8x8 pans. I decided to put it all together in one 9x13 pan instead, which is slightly less total volume than the two pans. This made for a very full lasagna pan, which is why I kept it covered in foil for the full baking time, so that the sauce wouldn’t spill over in the oven (although a tiny bit still did). If you’d rather split the lasagna into two pans, remove the foil halfway through cooking.
