This Rustic Tomato Onion Galette Is Seriously Healthy
How to make this tart part of a healthy Mediterranean diet.

The Mediterranean diet may readily bring to mind countries like Italy, Turkey, and Morocco, but many people forget that France is included in this region as well! The southern coast of France is heavily influenced by Mediterranean flavors and uses traditional heart-healthy ingredients, but with a French twist.
This Tomato Onion Galette is the perfect example of a French take on the Mediterranean diet. A galette is a rustic, free-form tart that can be made either sweet or savory. It is best described as a cross between a pizza and a pastry. Galettes are common in France (as is anything with pie dough; sigh!), and the tomato-onion filling in this galette recipe gives it the perfect Mediterranean touch.
In this episode of To Eat With Love, our Mediterranean diet cooking show, nutritionist Fiorella DiCarlo, RD, CDN, shows how to make a healthy version of the filling for this French galette recipe, with sauteed onions and tomato roasted with olive oil, salt, and garlic. Roasting the tomatoes gives them a more succulent, less acidic flavor and makes lycopene easier for the body to use.
For the dough, you can essentially use any pie dough, but it’s best to stick to one made from complex carbs instead of refined, white flour. Many stores sell prepared whole-wheat pie doughs, or you could make your own. You can also make galette dough with buckwheat flour or a gluten-free blend. (And TBH, some people just use frozen puff pastry. It’s less authentic, but it gets the job done.)
When you fold up the galette, don’t worry too much about technique. Simply fold the edges of the crust inward. It doesn’t need to be perfectly round (in fact, it might have more of an octagon shape). Some bakers will crimp the edges of the galette with a fork, but this is totally optional.
This vegetarian galette makes a great brunch recipe, and it is a low-stress—yet seriously impressive—option for a busy host, thanks to its rustic, no-frills form.
Ingredients
- 1 (13.8-ounce) can refrigerated pizza crust dough
- 12 small fresh plum tomatoes
- 2 tablespoons extra-virgin olive oil
- 1/4 teaspoon salt
- 5 cloves garlic, unpeeled
- 1 teaspoon water plus 1 tablespoon, divided
- 1 tablespoon extra-virgin olive oil
- 5 cups sliced red onions (about 1 1/2 pounds)
- 1 tablespoon red wine vinegar
- 2 teaspoons chopped fresh thyme, divded
- 4 ounces crumbled goat cheese
Instructions
1. Preheat oven to 375ºF. 2. To prepare tomato layer: Cut tomatoes in half lengthwise. Place cut-side up on a large, rimmed baking sheet. Drizzle with 2 tablespoons olive oil and 1/4 teaspoon salt. Place garlic cloves on a square of foil and sprinkle with 1 teaspoon water. Wrap into a package and place on the baking sheet. Roast until the tomatoes are very soft and beginning to brown on the bottom, 1 1/4 to 1 1/2 hours. 3. To prepare onion layer: Meanwhile, heat 1 tablespoon olive oil in a large skillet over high heat. Add onions and 1/2 teaspoon salt and cook, stirring, until just starting to lightly brown, 3 to 5 minutes. Reduce the heat to medium-low, cover and cook, stirring occasionally, until very soft, 30 to 35 minutes. Stir in raisins, vinegar and 1 teaspoon thyme. 4. Unwrap garlic; when cool enough to handle, squeeze out of the skins into a small bowl. Add 1 tablespoon water and mash together into a smooth paste. 5. Increase oven temperature to 400ºF. 6. To roll out pastry: Place a large sheet of parchment on a work surface and dust it with flour. Place the pastry disk in the center and lightly dust with flour. Roll out into a 15-inch circle. The pastry may crack a bit as you roll it, so go slowly and just nudge the cracked parts back together, pressing lightly. Dust with more flour as needed and keep the circle as even as you can, but don't worry about rough edges. 7. To assemble & bake: Spread the onion mixture over the pastry, leaving a 2-inch border around the edge. Spread the garlic paste over the onions. Place the tomatoes, cut-side up, on top of the onions in a circular pattern. Scatter cheese over the tomatoes and sprinkle with the remaining 1 teaspoon thyme. 8. Use the parchment paper to lift the edges of the pastry and fold loosely over the filling in 2- or 3-inch sections at a time. The pastry may crack as you lift and fold it, but that's fine. Lift the galette on the parchment and transfer it, parchment and all, onto a baking sheet. Trim off any overhanging parchment. 9. Bake the galette until the filling is bubbling hot in the center and the pastry is golden brown, 30 to 35 minutes. 10. Let cool at least 15 minutes on the baking sheet. Lift parchment and galette onto a serving platter. Use a spatula to very slightly lift the galette so you can slide the parchment out. Serve the galette hot, warm or at room temperature.Nutrition Information

00:00:00,000 --> 00:00:04,852
We're cooking with the aromatic flavors
of French country cooking today,
2
00:00:04,852 --> 00:00:06,915
with a tomato, onion gallete.
3
00:00:06,915 --> 00:00:11,729
[MUSIC]
4
00:00:11,729 --> 00:00:15,011
We're gonna start with
roasting our tomatoes.
5
00:00:15,011 --> 00:00:18,448
These tomatoes offer a lot of
vitamin C and lycopene, and
6
00:00:18,448 --> 00:00:22,616
fiber that's going to add a great
nutritional content to this meal.
7
00:00:22,616 --> 00:00:28,579
We're gonna take our olive oil and
drizzle it right over our tomatoes.
8
00:00:28,579 --> 00:00:32,114
The fats in the olive oils are going
to allow you to absorb more of
9
00:00:32,114 --> 00:00:33,725
the lycopene in the tomato.
10
00:00:33,725 --> 00:00:37,080
Now we're gonna take our sea salt and
we're gonna sprinkle our tomatoes.
11
00:00:37,080 --> 00:00:39,850
France is also very well known for
their fleur de sel,
12
00:00:39,850 --> 00:00:41,940
their very famous sea salt there.
13
00:00:41,940 --> 00:00:45,520
So if you get your hands on that,
that would be great to add to this recipe.
14
00:00:45,520 --> 00:00:49,400
And we're going to work with our garlic
which is going to be a very pivotal
15
00:00:49,400 --> 00:00:51,400
ingredient in this recipe.
16
00:00:51,400 --> 00:00:53,899
It's full of antioxidants and.
17
00:00:53,899 --> 00:00:57,873
It's gonna be very antimicrobial and
anti-inflammatory.
18
00:00:57,873 --> 00:01:00,260
We're gonna put a little
bit of water here.
19
00:01:00,260 --> 00:01:02,750
So it steams in this little package.
20
00:01:02,750 --> 00:01:06,841
And we're going to close it up there and
and just add it to our sheet pan.
21
00:01:06,841 --> 00:01:09,371
So it goes into the oven together, okay?
22
00:01:09,371 --> 00:01:12,987
Our oven is set at 375 degrees.
23
00:01:12,987 --> 00:01:17,026
And this is going to cook for
about a little over
24
00:01:17,026 --> 00:01:21,904
an hour until it's soft inside and
brown on the bottom.
25
00:01:21,904 --> 00:01:25,237
What is not commonly known is
that tomatoes are not indigenous
26
00:01:25,237 --> 00:01:26,334
to Mediterranean.
27
00:01:26,334 --> 00:01:30,965
They were actually exported in the 16th
century by the Spanish conquistadors
28
00:01:30,965 --> 00:01:32,635
coming from South America.
29
00:01:32,635 --> 00:01:35,629
But as soon as they got their hands on it,
they went wild.
30
00:01:35,629 --> 00:01:36,364
If it was to me,
31
00:01:36,364 --> 00:01:40,418
I'd roast all my vegetables because
it just enhances the flavor of them.
32
00:01:40,418 --> 00:01:42,720
So I'm gonna go ahead and
put this here and
33
00:01:42,720 --> 00:01:45,860
we're going to begin to
assemble our galette.
34
00:01:45,860 --> 00:01:49,400
You can fill these crepes and
these galettes with so
35
00:01:49,400 --> 00:01:55,132
many different ingredients from savory
to ham and eggs, to vegetarian versions.
36
00:01:55,132 --> 00:01:58,630
Our gallette is normally made
of a buckwheat flour, but
37
00:01:58,630 --> 00:02:00,970
today we're going to use a regular crust.
38
00:02:00,970 --> 00:02:05,540
The key to controlling blood sugar levels
if you don't have a whole grain crust
39
00:02:05,540 --> 00:02:07,760
is just to add more fiber.
40
00:02:07,760 --> 00:02:11,400
Okay, so the first thing we're gonna
do is we're gonna add our red onions
41
00:02:11,400 --> 00:02:14,440
that had been sauteing with
red wine vinegar and thyme.
42
00:02:14,440 --> 00:02:19,425
Go ahead and put that right in
the middle of our gallete here.
43
00:02:19,425 --> 00:02:23,363
And what you want to do is you wanna
leave about a two-inch space around
44
00:02:23,363 --> 00:02:27,187
the perimeter of the gallete because
we're going to fold it later.
45
00:02:27,187 --> 00:02:31,986
Next, we're going to put in that
crushed garlic that we put in the oven.
46
00:02:31,986 --> 00:02:38,123
We're gonna go ahead and just smear
it on evenly in chunks, no worries.
47
00:02:38,123 --> 00:02:41,173
Because again we're doing
it rustic style here.
48
00:02:41,173 --> 00:02:45,160
So we're gonna go ahead and get our
beautiful tomatoes now and add them on.
49
00:02:45,160 --> 00:02:47,600
There we are, just beautiful.
50
00:02:47,600 --> 00:02:52,690
And France is known for its wonderful
bread and tarts, and these galettes.
51
00:02:52,690 --> 00:02:56,470
The burst of colors here is with
the purple and the reds look beautiful.
52
00:02:56,470 --> 00:02:58,820
You're gonna wow your guests.
53
00:02:58,820 --> 00:03:01,490
There we are, I'm gonna put that there.
54
00:03:01,490 --> 00:03:03,900
Perfect, I think that's just enough.
55
00:03:03,900 --> 00:03:06,720
And next,
we're going to add our goat cheese.
56
00:03:06,720 --> 00:03:10,900
So this is a very famous cheese in France,
our formage, our chevre,
57
00:03:10,900 --> 00:03:12,179
if you wanna be fancy.
58
00:03:13,640 --> 00:03:15,050
There we are.
59
00:03:15,050 --> 00:03:19,208
And what we're going to do next and
finally, is add our thyme and
60
00:03:19,208 --> 00:03:23,141
the essential oils, and
antioxidant powers of this thyme.
61
00:03:23,141 --> 00:03:29,575
Plus the flavor is gonna really
enhance this hearty vegetarian meal.
62
00:03:29,575 --> 00:03:32,657
So now, we're gonna assemble the sky,
okay so here,
63
00:03:32,657 --> 00:03:35,750
don't worry about breaking
a little bit of the crush.
64
00:03:35,750 --> 00:03:39,510
You can kinda patch it together as you go,
it doesn't have to be perfect, okay?
65
00:03:39,510 --> 00:03:41,450
And some are going to overlap.
66
00:03:41,450 --> 00:03:44,711
There, perfect, look at that.
67
00:03:44,711 --> 00:03:49,689
[MUSIC]
68
00:03:49,689 --> 00:03:53,969
Okay, very rustic, there we go.
69
00:03:53,969 --> 00:03:58,372
Just gotta make sure, so
when it bakes, it doesn't ooze out.
70
00:03:58,372 --> 00:04:00,725
And that's lovely and perfect.
71
00:04:00,725 --> 00:04:04,154
We've raised our oven temperature
to about 400 degrees, and
72
00:04:04,154 --> 00:04:06,848
we're about to put our
galette onto our sheet pan.
73
00:04:06,848 --> 00:04:10,646
Now we have our sheet pan upside down,
because it will be easier,
74
00:04:10,646 --> 00:04:13,640
when it's finished,
to come out and take it off.
75
00:04:13,640 --> 00:04:15,510
So we're gonna go ahead and
put that like that.
76
00:04:16,790 --> 00:04:19,254
And slide our parchment paper and
77
00:04:19,254 --> 00:04:22,779
the galette right onto
the sheet pan very easy.
78
00:04:22,779 --> 00:04:25,756
Again, the oven temperature
is now up to 400 degrees,
79
00:04:25,756 --> 00:04:27,533
and we're gonna go slide this in.
80
00:04:27,533 --> 00:04:36,798
[MUSIC]
81
00:04:36,798 --> 00:04:40,790
Okay, we've pulled out our lovely galette
from the oven, and it has been cooling for
82
00:04:40,790 --> 00:04:42,430
about ten minutes.
83
00:04:42,430 --> 00:04:47,380
I'm going to add just one more final
touch of thyme to give it a final
84
00:04:47,380 --> 00:04:49,430
aromatic touch.
85
00:04:49,430 --> 00:04:50,549
There we are.
86
00:04:50,549 --> 00:04:51,830
It's beautiful.
87
00:04:51,830 --> 00:04:57,500
We have this beautiful, hearty vegetarian
peasant dish from the south of France.
88
00:04:57,500 --> 00:04:59,289
I'm Fiorella, and I'll see you next time.
89
00:04:59,289 --> 00:05:05,069
